This guy play 50 matches per season in high intensity EPL, injury free.
In my oponion, the problem is different for him, my take is he is not that kind of player that really understand tactics and positioning, those glorified thing of Calcio. All of his programs currently to make him learn the tactic and adept to it, so he will know where he need to be in certain situation. So until he familiar with Italian way of play he will be out injured based on agreement
