i think our best midfield would be
gundo - ramsey
---- ozil ---
walcott - alexis
giroud/welbeck
i'd prefer we sit two midfielders deep and they are given explicit instructions that when one pushes forward, the other sits. both have a good enough engine to do that. id actually say their defending skills are pretty similar. ozil would then have 2 wide runners and a central striker to feed.
the other midfield option would be to sit one midfielder deep, with two box to box types in front. but in that setup, i dont think it works to use ozil as one of those 2. we'd have to play a diamond, with one DM, two CMs, and then ozil at AM, with 2 attackers ahead of him, which would likely make us too narrow, especially since our fullbacks provide fuckall
wenger changed the formation this year. i guess its tough to know which players would fit best unless we know what he plans to do with ozil and the formation as a whole. having alexis, walcott, ozil, welbeck, giroud, cazorla, ox, and ramsey all fit at the same time will give him a bunch of selection options.
