Sir Alex continued: “That was disappointing, actually, when you think of the number of players we’ve given Sunderland over the years.
“I think we gave them the players that got them promoted: Evans and Simpson. But I don’t think it was malicious; it was them enjoying the moment. I don’t think it was anything against Manchester United really.
“I don’t think revenge will come into it tomorrow. Winning the game is more important to us. And given the impetus we got from last week, hopefully that will be a decider for us.
“It’s time for us to really kick on and make sure we maintain our lead at the top of the league.”
