Anderson has come in for lots of stick since joining United.
Injuries amongst other things have derailed his progress as a player and whilst he had shone he failed to do it consistently.
But towards the end of last season he began to string good performances together as well as getting amongst the goals.
And following a good preseason, his first at the club despite joining in 2007, he has carried it on this season to the pleasure of Sir Alex.
“He’s been tremendous, the boy.
“He’s had a couple of long-term injuries which haven’t helped him, but in the last year or so, he’s steered clear of injury.
“That means he’s training every day so his fitness levels are much better. And he’s maturing so you can see the consistency in his game.”
