For a couple of years with us gio was one of the best players in the world with the ball at his feet. Whilst messi of course is a better all round player, gio had that ability to run at people and past them with the ball appearing to be stuck to his feet. It's a rare skill, you dont see these players very often. Maradona had it, Messi's got it and for a very short period a shit team with a shit manager and a shit chairman got lucky. Silva is the nearest thing we've got now: a playmaker who makes goals out of nothing. Bit silva can't go past people like gio did.
The problem for gio was injury. He got a knock or two in his last season with us and then another more serious one early in his career at Ajax I think. He also put weight on and he suddenly lost the burst of pace which took him past people. This rendered him a shadow of his former self as he'd lost his biggest asset.
But don't let the revisionists on this thread kid you: for a while he was absolutely mesmerising and the talk of football. I've never seen a better player at going past people as if they weren't there. At that part of the game at least, for two years, he was as good as messi is now.
