"He's being booed even though he's won the Champions League, FA Cups and Premiership titles. But if it's good enough for him it's good enough for me.
"I think it's bonkers. I went to Old Trafford on Tuesday and the fans were chanting his name. Maybe they felt guilty. But this is Alex Ferguson we're talking about and he won't have lost any sleep over it.
