I agree he was decent. Decent isn't good enough for a great club like Manchester United though, hence why he was sold for q very low fee.
Christ, wasn't Nani named Player of the year once, by his United peers? You talk like Nani had a career like Bébé, Januzaj or something. Plenty of important United players in the past have been sold for low fees. Does that make people neglect their careers on a whole? Nani wasn't Ronaldo but he has nothing to be ashamed of concerning his United career. He did well.
