Chelsea chief Ron Gourlay says Carlo Ancelotti has the team playing it's best football since the arrival of Roman Abramovich.

Victory for the Blues against Manchester United will take them five points clear of United in the Premier League title race.

"I want to get Stamford Bridge back to being a fortress," said Gourlay. "The signs are there that opponents are starting to fear coming to the Bridge again. We went through a period when that fear was taken away but that's coming back.

"These are exciting times again. We're playing the most entertaining football we've played in the last two or three years. Personally, I think anybody who finishes above Manchester United will win the League. I do see them as our biggest rivals."
