I'll change my grade and go for a 4/10.
I don't like the way the squad was constructed. Giving Coman away as a clear mistake, idiotic move by Marotta, who got fooled by Schalke/Draxler. Again he moved a guy without being sure he would get his replacement - alas Vidal.
Khedira so far is a terrible signing, an expensive player who is only decent at midfield, but will struggle to be healthy.
Midfield got very thin, we lack options in attack (Zaza's deal was also terrible), no AM, while spending more than 60M net.
I just say this wasn't a total bust because Alex Sandro, Dybala and Rugani (allegedly) are very talented, Neto as good (while having little impact on the squad for now), while Hernanes, Mandzukic, bring some needed experience. Lemina can't be judged yet. Cuadrado adds flexibility but doesn't really fit the squad.
The current best team we have is:
Buffon
Licht
Bonucci
Chiellini
Alex Sandro (UPGRADE ON EVRA)
Marchisio (UPGRADE ON PIRLO AS A DM)
Pogba
Hernanes (HUGE DOWNGRADE ON VIDAL)
Pereyra
Dybala (DOWNGRADE ON TEVEZ, BUT NEARLY THE BEST REPLACEMENT AVAILABLE, COULD KEEP LEVEL BY THE END OF SEASON)
Morata
This starting team could gel and actually be able to keep last season's level. But Allegri will have to do his job. He's not helping Marotta's mercato evaluation so far.
Bench: Neto, Caceres, Barzagli, Rugani, Evra, Padoin, Lemina, Sturaro, Cuadradado, Mandzukic, Zaza.
Squad is unbalanced, desperately need an AM, at least a prospective young one, to be an option on the bench, and a SS, since Cuadrado, at first sight, is not one. (we had it in Coman. What a stupid move)
