Vidal was okay but wasteful in possession.
Pirlo was okay.
Marchisio had a bad game, but that just means he doesn't do anything positive - he still doesn't harm the team.
Pogba did all that could be expected of him in the circumstances, but he can't have been at more than 60%.
The more I think about it, the more I think the forwards were the bigger problem. They offered virtually nothing prior to Morata scoring.
