I understand the problem of having three attacking midfielders and no real wingers from a tactical point of view; the danger is that the middle of the park will become congested and there'll be loads of space down the sides left open with no one attacking it. Personally I'd always look to emulate the Bayern frontline with two Ribery/Robben-esque wingers flanking a central striker. But if a player of Fekir's quality becomes available I don't think Wenger will care one bit, and I'd be very excited to have him. Firstly it's not impossible to instruct Fekir/Özil/Mkhi to interchange positions and stay wide at different times. Secondly I just think his quality will stand out. Some of those wingers mentioned above are great players and I'd like to see a few of them at Arsenal, but none of them have (or are yet to have) that outstanding talismanic quality that Fekir produces. Auba/Laca/Özil/Mkhi/Fekir would be an outrageously talented set of attacking players to have in a squad. You'd just have to sort out the shambles going on behind them.
