Sir Alex is prepared for a tough tussle at Chelsea after admitting Andre-Villas Boas has changed the style of the Stamford Bridge outfit.
The Blues have regularly competed for top honours with United since Roman Abramovich bought the West Londoners and the manager is relishing the chance to improve on a relatively poor recent Barclays Premier League record at their home.
“In the last seven years, there have been battles with Chelsea,” he stated. “In the previous decade, it was Arsenal. There have been terrific battles between us and Chelsea. The manager has brought in two or three different players and I noticed when we played them in the home game earlier in the season there was a change in the style from the previous Chelsea teams.
“When a new manager comes in on the back of someone so successful like Carlo Ancelotti, changes maybe take time. Everyone has their different philosophy and their different ways of doing things and I think that’s what we’re seeing with Chelsea at the moment.
“It was a crazy game at Old Trafford earlier in the season – it could have been 20-18! I don’t think it will be like that on Sunday. I think it will be much tighter.”
