Gio needs time to prove himself, and I am sure he will have ample opportunities this season. However, he needs to get more involved in the game, and track back to win the ball, not just wait until it comes to him.
Del Piero is not getting any younger, Diego can't start every game, and Trez already has his mind elsewhere, so Gio will definitely have the chance to prove himself.
As for Criscito, I sincerely hope he comes back. He is clearly a class player, and will only get better. I don't blame him one bit for behaving the way he does, because we didn't show any faith or have any belief in Him. For all those haters (and you know yourselves), get your facts straight, stop reading too much into the media BS, and give the kid a break.
