"People talk about money and all the stuff that goes on around football, but to me, it just comes back to winning," he said.
"It doesn't matter how much money you have, at the end of your career, what you will be most proud of are your achievements.
"If you have won things and continue to win things for this great club, that is something to talk about.
"I wouldn't sit down and talk about how much money I have. It would be more to do with what good times we had and some of the sorrow moments, when we lost games we should have won.
"Football is the most important thing. At Manchester United, winning is definitely at the top of everyone's agenda."
