Well, those niggling injuries will probably persist at his age. A stop-start season doesn't help. Allow me to be more specific. He may be fit, but if he can't play enough, he'll be lacking in sharpness and match fitness. We can't rely on Marchisio as our only quality backup in the 4-2-3-1 formation. Hence, we need another quality CM to come in and relieve the pressure off Pjanic and Khedira. I'm also skeptical as to what shape Khedira will be in next season. We have been fortunate that he didn't sustain any serious injuries last season, but we can't go a full season having to rely on both him and Marchisio without viable alternatives. I don't want to see the likes of Rincon and Sturaro getting extended game time. That would be far from ideal.
