From a outsiders perspective ,i would have to say everything about your first 11.You dont have one single world class player in your first 11,there all mediocre to good at best.
The good ones are : Krasici ;Quagliarella ;Mello &Chiellini ,the rest are mediocre players.Buffon is the only truly world class player you have left,but his injured ATM.
I know some of you may think some of the players i listed are world class,but just do your self a favor and look back a few years at what players you had playing for your team.
