Italy say goodbye, Ireland say hello. To the quarter-finals of the World Cup of course. And it is also time for us to say cheerio - until Tuesday when the World Cup resumes with Canada v Romania and Uruguay v Fiji.
And talking of farewells, a big-name Premier League football manager is leaving his job. Who? Head over to our live reaction page to find out...
Coach reaction - Schmidt
Ireland 16-9 Italy
Ireland head coach Joe Schmidt on next weekend's table-topping clash against France: "France are another level up - we will have to raise our game again. We work on that this week and hopefully we can come up with the goods."
Coach reaction - Schmidt
Ireland 16-9 Italy
Ireland head coach Joe Schmidt: "That game was exactly what we expected. We have been allowed to cruise through the first two games and it was shock to the system to come against a tier one side who needed to win to stay in the tournament.
"I said last week we'd take a one-point win, so a seven-point win is good enough."

Stats of the day
Ireland 16-9 Italy
Ireland have now won 20 of their last 21 games against Italy
However, this was Ireland’s narrowest victory over the Azzurri since February 2011 having won by 23+ points in each of their four wins since then
Pool D as it stands
Ireland 16-9 Italy
Sorry for sounding like a broken record but it is important. Very important. Ireland's win books their place in the quarter-finals, while Italy's wait to reach the knockout stage for the first time goes on. And here's the confirmation....

Ireland shaded most departments against Italy, but one stat really jumps out - at the line-out. No pun intended there...
The Italians failed to collect 12 of their 17 throws, while Ireland continued their impeccable line-out record in the tournament - winning all 10 of their attempts.

Ireland captain Paul O'Connell: "We have won and are into the quarter-finals, that's the bonus. It was a disappointing performance, very inaccurate, and we have put too much ball down. When we do that we can't play our game and it interrupted our rhythm. A great try-saving tackle from Peter O'Mahony saved the game for us.
"It is going to be a massive game against France, who are playing good rugby. We have to massively improve from this performance."
Ireland 16-9 Italy
The Irish also made more metres (386-300), made more carries (126-105) and beat more defenders (20-10).
The one stat that Italy did dominate was the number of tackles made - 146 to Ireland's 90.
It may have been a hard-fought win for Joe Schmidt's men, but it was a win nonetheless.

The Irish victory means Joe Schmidt's men are assured of a place in the quarter-finals. And that sets up a humdinger of a final game against France - the winner taking the group and avoiding the All Blacks in the last eight.
No such luck for the Italians though. The Azzurri are heading home. After their final Pool D match against Romania of course.

Untidy stuff from the Ireland pack allows Italy to counter down the right flank, but an offload goes stray and allows Simon Zebo to gather. Chance gone. And that sets up an Ireland attack...

Ireland have been dominant at the line-out today, but can't nick another Italian set-piece inside their own 22. Azzurri scrum-half Edoardo Gori boots clear the danger, but referee Jerome Garces decides to collar Peter O'Mahony for a high tackle. The Frenchman shows the yellow card.

Ireland, whose overall possession percentage has now ticked up to 58%, are also starting to dominate the other attacking numbers.
They've now made now metres (299-223), more carries (102-77) and beaten more defenders (14-5).
Although how many of those beaten defenders is actually just Simone Favaro being given the runaround, we can't confirm...

Little under 20 minutes left. That's 20 minutes for Ireland to hold on and book their quarter-final sport. Or it is 20 minutes for Italy to mount a courageous comeback and save their World Cup skins?

Ireland commit a lot of numbers to that attack and are susceptible to some serious danger on the counter.

There's been nothing to separate the teams in terms of possession, and the attacking stats have been pretty close too.
Ireland have made 176 metres to Italy's 156, 60 carries to their 62 and 56 tackles to their 68.
In contrast to the match between Argentina and Tonga, which saw 63 missed tackles across the 80 minutes, there have been just nine in the first half at the Olympic Stadium.

Italy thought they had made it to the break without further punishment after that scrum infringement. But they almost came a cropper after switching off in the dying moments. The Azzurri lose the line out and, after Ireland quickly move the ball out left, Keith Earls almost dances his way through a gap. However, his offload finds touch and that brings the first half to an end.

Johnny Sexton has another chance to add to Ireland's score after Quintin Geldenhuys lifts the legs of his opponent in the tackle.

I think we will see another very well organised Ireland performance. Maybe not showing a huge amount but doing enough to win the game by a similar margin to the 36-6 win over Italy at the last World Cup.
A lot of the Italian players have got a little bit older and the probably don’t have the same physical threat that they had two, three, four years ago. Parisse is their one world-class player. Even when they are beaten, he invariably looks outstanding but will he be able to produce his best after his recent injury problems?

Because Ireland - the best team in the northern hemisphere - are not only expected by many of their supporters to cruise into the last eight, but also to reach the last four.
Ireland have already picked off Canada and Romania with consummate ease, are fancied to do the same against Italy today, thus setting up an almighty scrap with France for the right to top Pool D.

Expectation is omnipresent in elite sport. Expectation from the media. Expectation from your supporters. Expectation from the players themselves.
Some nations have shown they can cope and thrive under this lead-like weight. The All Blacks at the last World Cup, for example. Others, like *cough cough* England, have crumbled.
Ireland, unlike those two examples, are not burdened by being the host nation. But back-to-back Six Nations mean the millions watching from across the Irish Sea - and around the world - are expecting Joe Schmidt's side to produce their nation's best World Cup performance.
Some - gulp - even reckon they are going to win it...

Ireland 16-9 Italy
The full-time action areas suggest that, while Italy kept them honest, Ireland deserved their victory, with 57% of the possession and having had the better of the territory.

The win is the important thing. It is three wins out of three and Ireland are in good shape going into the final pool game against France. Next Sunday's game is absolutely huge. They have both qualified and the aim now is to avoid the All Blacks.

Ireland 16-9 Italy
The Irish victory means Joe Schmidt's men are assured of a place in the quarter-finals. And that sets up a humdinger of a final game against France - the winner taking the group and avoiding the All Blacks in the last eight.
No such luck for the Italians though. The Azzurri are heading home. After their final Pool D match against Romania of course.

And that's it - all over! Johnny Sexton receives the ball and sticks his boot straight through it to find touch. Ireland needed to win - by hook or by crook - and that is exactly what they have done.

This to seal the match then. But Ireland fly-half Johnny Sexton drags the kick left of the posts. Don't worry too much though, Ireland fans, there are just seconds left on the clock...
Ireland 16-9 Italy
Zebo is in the thick of the forward running, but then wastefully throws a forward pass as he looks for Tommy Bowe in support. Hang on - the referee doesn't give it! And then Italy give away a kickable penalty for obstruction...
Ireland 16-9 Italy
Untidy stuff from the Ireland pack allows Italy to counter down the right flank, but an offload goes stray and allows Simon Zebo to gather. Chance gone. And that sets up an Ireland attack...

Sin-bin - Peter O'Mahony
Ireland 16-9 Italy
Ireland have been dominant at the line-out today, but can't nick another Italian set-piece inside their own 22. Azzurri scrum-half Edoardo Gori boots clear the danger, but referee Jerome Garces decides to collar Peter O'Mahony for a high tackle. The Frenchman shows the yellow card. The Irishman cannot believe it.

Missed penalty
Ireland 16-9 Italy
The first job of the afternoon for Carlo Canna - Tommasso Allan's replacement - is to line up a kick at goal. But the Italy fly-half's kick from close to the halfway line lacks the legs and drops short of the Irish posts.
Replacement
Ireland 16-9 Italy
Time for a Italian change - and one that is not unexpected. Talisman Sergio Parisse - playing his first World Cup match after injury - trudges off after battling through an hour, despite only returning to training on Tuesday after a calf injury. Fly-half Tommaso Allan is also replaced.
Ireland 16-9 Italy
Ireland, whose overall possession percentage has now ticked up to 58%, are also starting to dominate the other attacking numbers.
They've now made now metres (299-223), more carries (102-77) and beaten more defenders (14-5).
Although how many of those beaten defenders is actually just Simone Favaro being given the runaround, we can't confirm...
Ireland 16-9 Italy
Little under 20 minutes left. That's 20 minutes for Ireland to hold on and book their quarter-final sport. Or it is 20 minutes for Italy to mount a courageous comeback and save their World Cup skins?

He's now missed five tackles - which is more than the rest of the Italy team put together (nine in total).
Penalty - Ireland 13-9 Italy
Johnny Sexton
A hush around the Olympic Stadium as Johnny Sexton lines up his fourth kick of the afternoon, teeing up just to the right of the Italian posts inside the 22. No problem for the Irish fly-half. Three more points nudge his team further ahead.

Here is the Irish onslaught. Johnny Sexton hangs a cross kick in the autumn air, knowing that Ireland have an advantage after an earlier Italian faux pas at the breakdown.

Ireland coach Joe Schmidt looks pretty glum, hand on chin, as he assess the danger from his lofty position in the Olympic Stadium stands.

Penalty - Ireland 10-9 Italy
Tommaso Allan
Italy might have been denied the chance of seven points, but the next best thing is to add three on their side of the scoreboard shortly after. Tommaso Allan gratefully accepts the chance to fire a penalty at the sticks, confidently walloping an arrow of a kick straight through. We have a game on our hands!
No try

Italy denied, Ireland relieved. Sensational last-ditch tackle from Irish back rower O'Mahony, who shoves Furno to ensure the Italian's left-foot touches the whitewash. No try.

Ireland commit a lot of numbers to that attack and are susceptible to some serious danger on the counter. Italian second-rower Josh Furno scampers down the left touchline and manages to get the ball down - he thinks. But did Peter O'Mahony bundle him into touch first? Let's go to the TMO to find out....

Half-time
Ireland 10-6 Italy
There's been nothing to separate the teams in terms of possession, and the attacking stats have been pretty close too.
Ireland have made 176 metres to Italy's 156, 60 carries to their 62 and 56 tackles to their 68.
In contrast to the match between Argentina and Tonga, which saw 63 missed tackles across the 80 minutes, there have been just nine in the first half at the Olympic Stadium.

Fit-again centre Robbie Henshaw has reminded Ireland exactly what he has to offer during that first half.

Half-time
Ireland 10-6 Italy
Italy thought they had made it to the break without further punishment after that scrum infringement. But they almost came a cropper after switching off in the dying moments. The Azzurri lose the line out and, after Ireland quickly move the ball out left, Keith Earls almost dances his way through a gap. However, his offload finds touch and that brings the first half to an end.
Ireland 10-6 Italy
Italy will be happy to see this through to the break. Scrum time - and you can bet your bottom Euro that the Italians will be looking to force an Irish error here. That is exactly what they do, prop Matias Aguero milking a scrum infringement to give his team some valuable breathing space.

Johnny Sexton has another chance to add to Ireland's score after Quintin Geldenhuys lifts the legs of his opponent in the tackle.

Irish indiscipline gives Italy another sniff. This time the Irish are punished for not releasing in their own half, but redeem themselves by nabbing the line-out when the Italians kick into touch. The Irish have been dominant in the set-piece so far, winning all of their three line-outs.

Breakthrough for Ireland! Joe Schmidt's men disrupt the Italian lineout for the first time - and it pays dividends. The hard-working pack set up the platform by going round the corner before the recycled ball is popped back inside by Robbie Henshaw for fellow centre Keith Earls to scamper through.

David Humphreys

I think we will see another very well organised Ireland performance. Maybe not showing a huge amount but doing enough to win the game by a similar margin to the 36-6 win over Italy at the last World Cup.
A lot of the Italian players have got a little bit older and the probably don’t have the same physical threat that they had two, three, four years ago. Parisse is their one world-class player. Even when they are beaten, he invariably looks outstanding but will he be able to produce his best after his recent injury problems?

Now I don't know whether Simon Cowell is a rugby union man or not, but if the high-trousered music mogul is watching the action in the Olympic Stadium then he would surely spot the talents of Italian powerhouse Sergio Parisse.
Italy were without the number eight against France and Canada, but have rushed him back from injury to face the Irish in a bid to provide a magic spark.
“That’s what we’ve missed, hopefully he will be on the pitch with us and he can bring that calmness and X-factor,” says team-mate Quintin Geldenhuys. “We need something extra and hopefully he can give it to us.”

So far Pool D has been more predictable than the sun setting in the evening. France and Ireland have won all their games, Canada and Romania have lost all their games, Italy are scrapping around in the middle.

And that takes us back to that 11-lettered, four-syllabled word which can be heavier than a Toulouse pack...expectation.
Because Ireland - the best team in the northern hemisphere - are not only expected by many of their supporters to cruise into the last eight, but also to reach the last four.
Ireland have already picked off Canada and Romania with consummate ease, are fancied to do the same against Italy today, thus setting up an almighty scrap with France for the right to top Pool D.
That honour, of course, would mean avoiding the All Blacks in the last eight, setting up an easy path into the semi-finals. In theory at least...
Post update

But we've been here before, haven't we? Ireland's 'golden generation' were expected to go deep into the 2007 World Cup - then got pitched alongside France and Argentina in that tournament's Group of Death. And Eddie O'Sullivan's side were bludgeoned by their pool rivals.
Failure to reach the knockout stage in France remains Ireland's worst performance at a World Cup. Eight years later, they will match their best by beating Italy today and reaching the quarter-finals.

Expectation is omnipresent in elite sport. Expectation from the media. Expectation from your supporters. Expectation from the players themselves.
Some nations have shown they can cope and thrive under this lead-like weight. The All Blacks at the last World Cup, for example. Others, like *cough cough* England, have crumbled.
Ireland, unlike those two examples, are not burdened by being the host nation. But back-to-back Six Nations mean the millions watching from across the Irish Sea - and around the world - are expecting Joe Schmidt's side to produce their nation's best World Cup performance.
Some - gulp - even reckon they are going to win it...
