Sir Alex Ferguson is hoping Manchester United can end their Stamford Bridge hoodoo and take another step towards regaining the Barclays Premier League title at the weekend.
United, who beat Arsenal 1-0 at Old Trafford on Monday night to establish a two-point lead at the summit with a game in hand, will move six points clear of fourth-placed Chelsea with a win on Sunday.
But they have not won at the Blues' west London home since April 2002.
Ferguson told Sirius XFM: "(It) is a massive game now. We used to have a terrific record at Chelsea, but not so much over the last few years and we haven't won there for eight years.
"It's a big game and we'll be ready for it.
"We've got good players and they have all had big-game experience for years now. Their experience is very important and the desire is still there with this club."
