in my opinion, our biggest issue is the ramsey/ozil choice. hear me out.
ozil's best position is behind the striker centrally. he can still do a job wide, but its not his best position and its easier for him to get isolated. to play behind the striker, we need to either play a 4-2-3-1 or a 4-4-1-1. we're not going to play 4-4-1-1. if we play 4-2-3-1, then either cazorla or ramsey need to play wide to get both in the team. cazorla doesn't have ramsey's work rate and pace, but hes more disciplined and has better positioning. ramsey, when played wide, sometimes seems to get lost and drift in/out of the game. when you play ramsey deeper, he tends to vacate and leave coq isolated, and that pushes cazorla wide, where he is less involved and can't dictate the play.
i think 4-2-3-1 is the best formation to get the best out of ozil and alexis. but unless ramsey's positioning improves, im not sure you can justify putting him in the team ahead of cazorla at CM. and as a winger, is he better than ox?
for all the talk of benzema, which im still fine with, we should be the ones bidding for reus. reus at LW and alexis at RW in a 4-2-3-1 with ozil between them would be bliss. sure, we'd have giroud/walcott to play striker and thats not ideal, but i think we need a winger just as much as a striker. i love ox and think hes got huge potential, but hes missed a lot of time.
either way, im not sure what is actually going to happen here. the other option i guess is to play a narrow 4-4-2 diamond, with coq deep, cazorla and ramsey in front, ozil at 10, and then giroud/alexis central. that actually might work. but i cant see wenger trying that.
