Kroos is confirmed, James is the next step. There's barely even a place for Isco on the bench the way things are going. Plus the news now is that Khedira actually wants to stay at Madrid. They're going to be massively stacked in midfield and out of Kroos, Modric, Alonso, James, Khedira and Isco there's only 1 midfielder there who Carlo has a reason to keep benched, and it's Isco as he pretty much flopped when asked to adapt to Carlos system.
He's definitely not added to his value this season, but he may not have subtracted any value either purely because he's at a club that doesn't need any money
If they ask for 30, pay up. We were close to that figure with Iturbe, we've just about sold Quags now too. The money is definitely there, we've made nearly 20M from sales (Maybe more) and our wage bill has been reduced significantly.
So if we can't spend 10M of our own money on a single starting XI player needed for a new system then upper management have no business running Juventus.
