West Ham United boss Sam Allardyce says Leicester City fans should get behind manager Nigel Pearson.

Pearson has accepted a Football Association charge of using insulting words towards a fan.

"There is a turning point because what happens at football clubs, expectation grows, people think you are just going to be able to go in there and be successful from a period of great joy," said Allardyce, who took West Ham up via the play-offs in 2012 and successfully retained their Premier League status.

"It is the fact that instead of watching your team win every week, it is a big adjustment for the fans when they find out it is not that easy any more.

"I suppose the expectation was built even higher when they beat Manchester United 5-3 and of course the Leicester fans have not remembered where Nigel has taken the club from and to in a short period of time, so they should show him a bit more patience and a bit more loyalty."
