London, Nov.4 Manager Sir Alex Ferguson sees Chelsea as the major threat to Manchester United's hopes of a fourth straight Premier League crown and a record 19th title in all.

United and Chelsea face each other at Stamford Bridge this Sunday in what has already been dubbed a potential title decider between the Premier League's top two sides, The Mirror reports.

"If United finish above Chelsea this season, they will almost certainly be celebrating the capture of another domestic title at Old Trafford," said Fergie.

"It's a very experienced team, that's the first thing. I said last year it's a team that can only improve results by the system they adopt. Their consistency, compared to last season, has probably been a wee bit better under Carlo Ancelotti," he added.

"Ancelotti's got the two strikers, and that is a major change compared to Phil Scolari and Claudio Ranieri. It's always a hard game at Chelsea, but we'll deal with it better than we did at Anfield, I'm sure of that," Fergie said.

"We're in the business of winning, and when we lose it has an impact in that you can't afford to lose many if you want to win this league. That's the starting point," he said. (ANI)
