I think, like Chelsea, a striker would solve most of your problems (probably applies more to Chelsea). If Arsene's feeling a bit adventurous though, could go for something like this.
LeftWing Ozil Walcott
-- Ramsey Wilshere
--------- DefMid
Draxler and Bender would fit in nicely there. All your best players are involved. You can go more narrow and direct with Ozil dropping off to make a diamond. If Fabregas was to return, he could rotate with any of Ozil/Ramsey/Wilshere. Defensively it's a bit **** (or a lot ****) but your players hardly track back anyway. Thank me later.
