Manchester City boss Pep Guardiola, speaking to Sky Sports: "We concede three or four counter attacks in the first half, they were clinical but I am more than happy for our performance. We pushed them, we created chances. In general I am happy with the performance. No regrets.
"I know who we are as a team. I am delighted to work with these guys. W tried and we tried in the second half. Unfortunate we scored late and could not turn the result.
"It is not time to think about that. We have to think about what we have to do and think about the next game. Doesn't matter if six, eight or 14 points we have to continue. We are a fantastic team."
'I congratulate my team'
Man City 1-2 Man Utd
Manchester City
Manchester City boss Pep Guardiola speaking to BBC Match of the Day: "Yes we lost 1-2 but I congratulate my team, my players were fantastic, we are a fantastic team.
"They are so fast, so quick and sometimes when you lose the ball it is more difficult. We tried, we got to the last third many, many times and they can run. Maybe a but more than usual."
On the title race: "We have to try to continue, there are many things to play for. It's difficult because the opponents are on an incredible run winning 15 games out of 16.
On reports of racism and it not being acceptable: "Of course not. I think the club are making a statement and I support that."
'You have to stick with the manager and the process'
Man City 1-2 Man Utd
Manchester United
Manchester United forward Marcus Rashford speaking to BBC MOTD:
"Especially in the first half it was enjoyable to play in. It's a tremendous feeling, we could have come in at half time three or four goals up.
"The boys were tremendous today, every single player, the challenge is to continue that. It was a good counter-attacking set-up and display, the negative is it was only good for 30-40 minutes. They have a lot of top quality players, and it can take it out of your legs a bit."
On his penalty: "I tried to stay calm and get the first goal. It's an important moment in the game, the main thing is it put us in a good position as a team. I had one from Fred that I misplaced and had one off the bar, so that could have been three or four goals up."
"It's been an inconsistent start to the season, it's a young team, and we've been trying to get the right fundamentals and the only way to get consistency is to go through these hard times. You have to stick with the manager and process. If we do that we've got something to be excited about in the future."
On reports of racism: "We seem to be speaking about it an awful lot over last six to eight months. Even speaking about it now is not nice. The necessary departments need to do the right things to stop it in the game. It is a big negative in the sport and the country."
Post update
There are two champions in action tonight in Europe's top five leagues.
Lionel Messi presented his sixth Ballon d'Or to the Nou Camp before Barcelona's game against Mallorca, which has just kicked off.
And former Ballon d'Or winner Cristiano Ronaldo's Juventus visit Lazio.
Manchester City deserve credit for the speed with which they have released that statement.
Football is a game that arouses passions, which is part of its charm. But there is a line that should not be crossed and those who do deserve to be punished.
Title challenge 'will be difficult'
Man City 1-2 Man Utd
Manchester City defender Kyle Walker, speaking to Sky Sports: "Us as defenders need to hold our hands up. We need to keep clean sheets and strikers maybe need to put more away.They had a game plan and it worked. They have quick players in quick areas and they are going to hurt you on the counter. Credit where credit is due, they stepped up today. Fair play.
"Can't fault the manager. He has won numerous trophies. I can't put my finger on it. It is going to be difficult, Liverpool are on fire. They are getting wins and we are not. It is a big gap but we will fight until the end."
'It's unacceptable'
Man City 1-2 Man Utd
Manchester United

"You defend so well but you are disappointed that you concede on a corner, which is not their strength but I can't complain to much.
"David de Gea is the best goalkeeper in the world. We've expected high standards off him and he is getting back to his best.
On reports of racist abuse: "I've seen it on the video, it was Jesse and Fred and the fella must be ashamed of himself. It's unacceptable and I hope he will not be watching any football anymore."

Rob: Note that the difference between United and City over this season is the number of draws. Both have lost 4 games.
Mike: City can kiss good bye the title. Even if there's an unlikely collapse by Liverpool, I just can't see City going on the type of run they would need to overhaul them.
