If we were to play 4-3-3, I don't think we will but if we would, I'd like to keep either Marrone, Ekdal or Gian in the squad as a backup even if we fetch a new CM.
I would personally welcome him, if we got a LW (Vargas, Ribery etc.) and a CB (Alex, Lugano etc.)
If he costs under €8m I think we should buy him because we don't have anyone else to play the regista role. He wasn't terrible last season and I'm sure under a better coach with better tactics :xfinger: he would flourish if Pirlo is injured/suspended.
