I personally prefer this:
---------Cassano - Zlatan
Nedved-Rosicky-Emerson-Camo
Chiellini-Cannavaro-Thuram-Zambrotta
-------------Buffon
No need to buy so much too many changes will make it harder for the team to adjust especially on defense so this is my lineup but I`m not sure about Chiellini
we can play 4-3-3 too with Nedved Emerson Camo at midfield and with Cassano Trez Zlatan in attack
