Nope.
I wouldn't call Nani a "disappointment" just yet. In glimpses he's shown some class but hasn't had a long enough run of games in the team, I think.
I was a massive fan of Nani when he was at Sporting Lisbon, but he's hardly set the heather alight at Old Trafford. He's only shown his real ability in spits and spurts and i for one expected so much more from him.
i think if ronaldo was to leave man utd we would see the best of nani
