Ahead of the Manchester derby at the weekend, United boss Sir Alex Ferguson believes the fight for this year's title is already a two-horse race between the Manchester clubs.
"It would be difficult to think the two of us would collapse and allow another team to get in so I think it will be between the two of us," he said.
"Derby games are notorious for surprises. City haven't lost for two years in it. It's going to be a hard game for us but we are capable of beating anyone."
