Manchester United boss Sir Alex Ferguson says Chelsea - not Liverpool - are their biggest title threat.

"People say every season, it's going to be three or four teams challenging for the title," said Ferguson. "But I'm of the opinion it comes down to two teams when you enter the last month.

"Chelsea have contested the league for the last four years and I think they have the experience to be our main rivals again. You have to think that will count for something. It's a change for Liverpool fans and players to even be talking about winning the league. They haven't been able to do that for 19 years, or at least a good few years.

"It was important for a team like Liverpool to get a good start. They needed it and it has given them a greater expectation. Experience is important, though. It's been proven every team will drop points. Experience teaches you to not drop as many as the rest."
