He was a celebrity footballer. If I had a choice of players from the period of squad from 1990 to 2013 , he’d not he starting . Madrid bought him for the marketing as much as anything else, had a pay per view medical if I remember correctly.
Also, he was sold because Ferguson felt his celebrity life was impacting his preparation. You could argue rashford will be sold for kind of similar stuff, if not exact same reason . Becks Going to book signings in London with posh spice and that stuff. He fit in at Madrid because ego was part and parcel of their galactico strategy.
Great player, great crosser but not somebody I’d be picking in my all time united team under Ferguson.
