Manchester United boss Sir Alex Ferguson insists he can't split title challengers Arsenal and Chelsea.

United play Chelsea - who trail them by a point - next weekend while Arsenal, who are a further point behind, do not have to face either of their title rivals.

Asked which posed the greatest threat to United, Ferguson said: "I don't think there is a bigger challenger, I think we are all in the pot together.

"On paper Arsenal have the easier run in, but only on paper. At this time of the season I'm not sure that works, whether it means anything at all.

"At the end of the day you can drop a couple of points like Chelsea did at Blackburn on Sunday.

"All of a sudden your advantage on paper doesn't look so good.

"The name of the game is to win your games and hopefully we can do that."
