Assuming the Rabiot and Iturbe transactions go through....
Spend: Coman (0), Rabiot (0), Iturbe (20m + Quags), Sturaro (5.5m)
Proceeds: Immobile (8m), Zaza (7m), Vucinic (6m)
So far: NET SPEND around 6m. Impact on wages is positive though - Coman & Rabiot would be on <0.5m each I reckon and Iturbe would be on 1.5m = <2.5m - Vucinic wages were 3m and Quags was also around 2m so saved >2.5m in wages while adding 3 players and losing 2.
If we play 433 we would currently have Giovinco, Coman, Tevez, Llorente, and Iturbe. Squad would be short a left back (as Peluso looks like he is going to Sassuolo in exchange for Marrone who will either be loaned out or used as a bargaining tool for another player) and another central striker.
No idea who the left back would be but I am sure Marotta wants to pay 2m to Real for Morata with the option to purchase with another 18m at the end of the season.
Wouldn't be surprised if Marotta sacrifices Ogbonna for a left back of equal value. Also expect Isla's 50% to be sold on. After all that, in terms of transfer fees, we would be square and the wage bill will be slightly better (also accounting for Pogba raise).
Squad could be:
GK: Buffon, Storari, Rubinho
DEF: Lichsteiner, Caceres, Barzagli, Bonucci, Chiellini, CB (loan or youngster), LB (transfer value 10-15m)
C. MID: Vidal, Pirlo, Pogba, Asamoah, Marchisio, Rabiot
Wingers: Iturbe, Coman, Pepe, Giovinco
Strikers: Tevez, Llorente, Morata
