I just thought that LDN in last game played with 451 to great success, hope he continues this way (thou he lacks players for all positions). But in the next season I would sell my mother to see formation like this filled with Mascherano and Pastore
Buffon
RB - Bonucci - Chiellini - LB
Mascherano
Pastore - Marchisio
Krasic ---------------- J.Mata
Matri/Quag
I recon Pastore/Mascherano combination would do Argentinian wonders

, it could be like great creative force Zizou with real pitbull fighter Davids, whilst Marchisio doing quiet job in supporting both of them in box-to-box role (I strongly believe he would excel in 3 man midfield.
Also I'm praying for Juve to get Juan Mata (unfortunately we are not linked with him) he would be excellent on left wing. Both with Krasic would run any defense ragged.
With such force in attack and midfield we could even get away with mediocre RB/LB. Attack is the best defense!
