We have some special talents who are all central midfielders with a mind to attack in Wilshere, Ramsey, Zelalem, and possibly AOC. When you then factor in that Özil recently turned 25, then at least I wonder how all this will pan out. All of these guys will need games to develop their potential, and realistically there are only 2 CM spots up for grabs for them in each game.
Wenger has found a way by predominantly playing AOC wide, and he is doing the same right now with Wilshere. You have to wonder if he can continue to find enough games for all of them when AOC is back and Zelalem comes into his own in a year or two. You also have to consider that Gnabry is another player vying for a spot!
