It looks like a formation you'd play in the last 10 minutes of the match, when you're 0:1 down and it's a must win match.
Yeah. That would be something Mourinho would play when he's down 0-1.
Quag-Aguero-Vucini all together would be plain stupid. Get one of Aguero or Vucini for SS position and not play them out of their positions and waste money because apparently we still need at least one decent buy.
Also, we fix our RB but then ruin or CB with Barzagli-Bonucci combination?

, we wouldn't be fixing much defensively.
Buffon
Lich - Bonucci - Chiellini - ?
Krasic - Melo - Pirlo/Marchi - ?
Quag - Aguero(if he signs)
