Sir Alex Ferguson is reportedly a little worried after Bolton already began celebrating their Premiership survival, and the Man Utd coach is concerned that the Trotters will not take their visit to Stamford Bridge as seriously.

"All you wonderful people in the press have been talking about the integrity of Wigan but nobody has questioned or even mentioned Bolton," said Ferguson. "I've heard about Bolton players out all week celebrating. And it's interesting, the different attitudes between them and Wigan. All we have seen this week are the Wigan players saying how they want to beat Manchester United. That's fine; I have no problem with that, because we are a big club. But when you hear about the Bolton players out all week celebrating that amazes me, that change in attitude.

"Both teams [Wigan and Bolton] are safe. Both teams are relaxed. But while one is all keyed up to play Manchester United the other is out celebrating.

"The only thing that gives me confidence about Bolton is their manager and their assistant manager. I have known Archie Knox for many years, at Manchester United and Aberdeen, and he will not enjoy hearing about his players going out celebrating, and neither will Gary Megson when there is such an important game."
