Lets just wait and see what Barca thinks about this...
He would be perfect as with him we wont have to buy CB anymore, he for me at least is also improvement on Marchisio.
Pogba, Marchisio, Khedira, Masche, Pjanic, Lemina and Sturaro is perfect for me. Sturaro might not be needed but with Khedira injury record and Marchisio problems he still might get plenty of games.
