Quagliarella, Aquilani, Bonucci, Sorensen, Krasic, Pepe, Storari.
These are all good players but I'm not sure they're all brilliant signings.
Quag was superb. I was pleasantly surprised by how he did with us.
Aquilani is hot and cold. Can be brilliant and can be absolutely shit.
Bonucci is consistent most of the time. Okay player.
Sorensen looks like a good future prospect. I think we need to strengthen that position further.
Krasic is our best signing. Just great.
Pepe is, again, a decent player. He wouldn't see the starting 11 in any top class European team.
Storari is good.
Motta is shit.
Traore is fine.
All in all if I had to assess Marotta's career with Juve so far, I'd say he's done well to provide a lot of squad depth. We really have a lot of good players; even compared to Inter or Milan. Our bench is much stronger than most of the teams in Serie A. That goes without saying, however, the problem with Marotta is with the exception of Krasic and perhaps Quag, he hasn't been able to sign great player that will take this team to the next level.
I would have preferred to get 2 more superb players instead of buying 10 good/average ones. But that's just me.
