Fergie now feels 82 points could be enough to win it - meaning his team need 25 from their final 12 matches, starting at Wigan Athletic.
The United boss said: "What I've said is that normally two teams break away.
"It looks like it might be interesting with a few teams involved but then as you get towards the end of the season there are always just two.
"That's the way it's looking at the moment. I think Arsenal or ourselves will win it."
