Of course it isn't right now. However, Marchisio will come back, Allegri will figure out how to use Pjanic in this team, and Lemina will likely improve as he gains more experience. Add to this Alves and Higuain gaining form and integrating with the team...
FFS, we started with 12 points in 10 matches last season and ended up winning a double, plus were just seconds away from beating Bayern.
I'm not happy with our start, but the overreaction is pathetic.
