He is a bad passer, has a bad first touch, and he's not very mobile, and that was all very clear to Atletico hence why they were very willing to let him go.
The idea of starting a striker because he is very good in the air is something a club like Stoke should do, not Juventus. Impact player. And a good one like that.
You don't see a limited striker like Chicharito starting at a big club either, because he is a liability around the park and it's difficult to play good football with him in the side. Same problem with Mandzukic.
