Man United boss Sir Alex Ferguson claims Ronaldo woud be making a big
mistake if he quits Old Trafford.

Ronaldo himself has repeatedly refused to commit his future to United
but his manager expects him to stay.

Ferguson said: "He signed a five-year contract last year and has four
years left. That's definite. I think he knows genuinely where the best
club is to be and that's Manchester United."

Speaking on United's tour to South Africa, Ferguson insisted a switch
to Spain would harm the player's career. "I honestly believe that could
be the worst thing he could do," he said.
