The secret to Leicester's success? Plastic clackers...

Former Foxes defender Matt Elliott has a theory as to why Leicester City top the Premier League table this Christmas.

"There are these plastic clackers, and now the whole stadium [...] everyone is sitting there banging these clackers, you've got 30,000 people all involved buzzing and singing, something as basic as that has changed it", he says.

The club placards double up as folding clapping boards and are handed out to 30,000 Leicester supporters before each game. According to Elliott, it generates the best atmosphere in the Premier League.
