When speaking during his weekly press conference at Carrington, he claimed the 26-year-old is very much part of his plans for the future.
“We want to keep him, there's no doubt about that,” Sir Alex stated.
“He's capable of scoring incredible goals. His goal against Everton, when he dinked the keeper after playing a couple of one-twos, was incredible. And the goal against Tottenham the year before, where he dinked the goalkeeper after playing a one-two, was another one.
"The boy has an incredible talent for winning matches. He's one of the best match-winners in the game, and I include the whole of Europe in that.
“David Gill's been speaking to his agent for quite a few weeks. It's entirely up to the boy - he has a year and a half left. I think he wants guaranteed first-team football. He can guarantee himself that. Performances like the other night can guarantee that.
"We're trying our best to keep him because he's such a match-winner."
