Nani was very good a couple of seasons back, but he hasn't got near that level since. I guess he just doesn't have the work ethic and discipline every day in training to stay at his best level. It's a shame because he has every tool you need from a physical and technical standpoint to be one of the best.
He's been a horrible little shit at United, the sort of arrogant tit of a player that United specialise in, but Wenger has a way of helping people to grow up and get the best out of themselves, and because of that if we signed him I'd remain open minded.
