Manchester United manager Sir Alex Ferguson congratulated Manchester City on their achievement.
He told BBC Sport:
Nobody expected that. Everybody expected City to win, but they did it against 10 men for half an hour and with five extra minutes to help them.
But I congratulate City on winning the league. Anybody who wins it deserves it, because it's a long haul.
At the end of our game our players didn't actually know the results. Now, they're really disappointed, I'm glad to say.
There's no other way they should be. They conducted themselves brilliantly today. Their performance level was good. I'm pleased at our performance this season. Eighty-nine points would win most leagues. It wasn't our turn today.
