After a great mercato and a promising start to the season I believe the squad still misses depth. The current squad might be enough to bring us Scudetto but as far as European glory is concerned IMO our squad depth is not enough considering the hectic fixtures and that many of our first squad players are in their respective NT's. Just take a look at squads of teams like Barca where they have a quality replacement at almost every department. In our case I think we need to improve our bench strength. Currently check our replacements
Grosso - Molinaro
Zebina - Grygera/Caceres(he needs more time)
Marchisio/Camo - Tiago
Melo - Poulsen etc.
Wat i'm tryin to say is we need decent replacements at various positions like what we have in Legro for CB or in the case of our strikers. Also considering the age of many our players like DP, Camo we should start making moves
Sissoko was injured so you can add him when he comes back I think he could make us better. Sissoko and Melo to neutralize our opponents
Grosso is a good temp solution for the LB
our RB is in need of improvement
and our strikers need to find the net. Iaquinta is a great player apart from his finishing ability he should improve it
Amauri is just unlucky apart from the Bayern match which he was invisible (IMO)
DP well when he gets back from injury we could talk (also strikers depth solved)
and Trez is the invisible striker that scores always been and always will be
so actually we are not lacking depth we are missing a right back
