I understand the financial situation and I'd like to think Sassuolo do as well. The fact is that Locatelli is pretty good but not good enough for PSG/Chelsea/City to come for him so Juventus is the best option. As a player, its likely that he'll win multiple trophies with us and get CL experience as a starter. I don't like how negotiations are going, we should have Sassuolo begging us or we just say f**k them and let Arsenal buy him at a discounted price since no other CL team is after him.
Also, players should no way be coming here looking for 6M+ wages unless they're certified world class - I guess previous management has set the precedent but Juventus should be a home for ambitious players. They need to realise that either you improve the team or your next stop is a transfer to some Serie B team as you'll get no time on the pitch.
Regardless of Locatelli, Allegri has a large and versatile squad. If the midfield is that shite then play Danilo as DM, Cuadrado in midfield and buy a RB. There are always different approaches and things that can be done like how Mandzukic was utilised. Utter garbage players should ride the bench until they request a transfer.
