Chelsea midfielder Michael Ballack believes the Premier League is a two-horse race this season between the Blues and Manchester United.
The Germany captain has dismissed the challenge of Liverpool, who are currently level on points with the Stamford Bridge club at the top of the table.
Reigning champions United are eight points adrift after failing to take advantage of draws for Chelsea and Liverpool on Saturday following their own stalemate with Aston Villa.
But despite the current gap between Chelsea and the Red Devils, Ballack still fears the side from Old Trafford more.
"It's always the big four that everyone speaks about but I think it's still about Chelsea and Man U," he told The Sun.
"Arsenal are already behind which makes it very difficult for them.
"Liverpool are very good at this moment but for me they are always a club for the Champions League, partly because they can put all their focus on one or two matches.
"But when you look at results and squads over the past couple of seasons as a whole, I think us and Man U are just a little bit stronger."
