Fergie admitted he could have done without a wise guy behind the away dug-out constantly taunting him with false information about Chelsea's progress against Bolton at Stamford Bridge.
"You have to try and dismiss all the stuff going on around you and concentrate on your own game," he explained. "But there was a guy behind me who kept telling me it was 2-0 for Chelsea so he did his bit."
Summarising the title race, he said: "It ebbed and flowed a bit. Arsenal looked like they would win it for a long period but they then dropped a few points after losing to us in the FA Cup and that made the difference. But we dropped points at Middlesbrough and Blackburn and that allowed Chelsea back into it."
Yesterday Avram Grant's side were undone by Bolton scoring late to draw at Stamford Bridge. But Ferguson said: "I think the two points they dropped against Wigan probably won the title for us."
