Wrong! We didn't buy Diego to play 4-4-2; hence, we don't need a left winger after Nedved retires, because we won't be adopting a system that requires the utilization of one. If we play 4-3-2-1 we can use Gio and Diego behind a lone striker; if we deploy a 4-3-1-2 formation, Diego can play behind Del Piero/Gio and Amauri/Trez/Iaq. In the event that we choose to implement a 4-2-3-1 formation we can play with 3 attack minded players across the midfield (namely Camo, Diego, and Gio) supporting Amauri or Trez.
We will, in all probability, be selling Tiago and disposing of Almiron in the nearest garbage can, so we might need to acquire a Hamsik/Asamoah/Xabi Alonso; however, that is not a necessity at this point in time, as we have Sissoko, Marchisio, Zanetti, and Poulsen who can all play as the 2 DM's in midfield. Ekdal will probably be loaned out to gain experience (I know Andy hates the thought of it, but it will happen).
Our main concern right now, the main focus of our mercato should shift to the defense. Buy a quality RB, sell Zebina and demote Grygera to the bench. If we can pick up a good quality CB, who has the potential to be WC in the process, then let's go for it.
IN: Canna, Diego, Liechsteiner, Guberti, Sakho, Criscito, Hamsik
Out: Molinaro, Zebina, Knezevic, Tiago, Marchionni, Almiron
If this were to happen, I will be more than satisfied with our Mercato.
