Giovinco played so much today just because it was snowing. Ranieri liked the risk of getting him injured, so he tried to capitalize in a last ditch effort to take the pressure from playing Seba off. Can't play him if he's injured.
Not at all, I don't like Juve and would be the first to jump on the "cheaters" bandwagon, but the penalty was solid. He dribbled past and approached the endline, the defender stabbed and Gio ran through with his right leg, he got clipped and it was pretty clear.
