I'd be upset to see Nasri go. If we are going to stick to this system of a mobile, creative front 3 behind a lone striker, then having 5 players from which we can pick any 3 (i.e. 3 from Sterling, KDB, Silva, Navas & Nasri) needs Nasri to stay. Our problem last season was that we had insufficient depth in those kinds of players
Actually, I think one of the most difficult jobs on the pitch is the 2 CM positions in our system. Our fullbacks bomb up the pitch constantly and the front 4, whilst working hard in tracking back & pressing, are far from the best tacklers on the pitch, so we rely on the 2 CMs helping out our defence a lot
Beyond yaya & on current form, fernandinho for those 2 positions, we have fernando & the unknown quantity of Delph (not quite sure his best position ?). I don't think any of the youngsters tipped to break through are in that position ? So CM is definitely the area another player would be most desirable
I don't see Zuculini as even being a matter for discussion - he's only in the squad this season if we happen to have room for him. I never saw the point in buying him and I made that very clear when we bought him (for which I was absolutely slaughtered on here at the time)
I can see fullbacks, who are performing well at the moment, being more an issue we will address over the next 18 months or so when some of ours get that bit older.
