Carlo Ancelotti admits that Manchester United are the favourites to win the Premier League after Chelsea’s 1-1 draw against Blackburn.
The Blues have dropped to third spot after the draw, and are outside the top two for the first time this season.
Chelsea's inability to secure maximum points against Rovers, along with Arsenal and Man United's wins, sees the Blues two points behind the Gunners and four points behind the Red Devils, and Ancelotti has revealed that his side is facing an uphill battle to bridge the gap.
"Manchester United are top of the league so are now the favourites," Ancelotti told the Daily Star.
"It will be more difficult now to win the title, but it is not impossible.
"This is not an easy moment for us, but we must not lose our confidence."
With Sunday's draw coming hot on the heels of their exit from the Champions League at the hands of Inter Milan, Ancelotti knows that a victory against Portsmouth on Wednesday is needed to resurrect Chelsea's flagging dream of silverware this season.
"Now we are third, it means we have to run more.
"We need to regain our momentum.
"But I still think we can do it although we must win our next game."
