The winger has lit up Old Trafford with his performances in the last couple of seasons and is worshipped by the fans at a level reminiscent of the adoration enjoyed by Cantona in the 1990s, but the Portugal international has repeatedly hinted at a "dream" move to Real Madrid this summer.

"I do not know his personality," Cantona said in an interview with Sport magazine. "I do not know why he would want to do this. It can be good reasons. If he says that he needs a new challenge, then maybe, yes, he is young. But if he goes not for that reason - for other reasons - then I think he is wrong."

He added: "He is the best player in the world - an artist. He is the best player in the world at one of the best clubs in the world.

"The way United play is perfect for him and the way he plays is perfect for United. It is a perfect situation."

Asked if he ever considered handing in a transfer request to United, Cantona replied: "Me? Never. I could never play for another club.

"But I am a different personality. I was 30 years old when I decided to retire."
