As much as i love Cazorla, i think he is the odd man out this summer in our midfield. Currently, he is forcing Ramsey out wide and while its not catastrophic in short term, it certainly cannot continue long term. Ramsey-Coq-Özil should be our starting midfield and on the right we should have Ox, or preferably an upgrade from transfer market (Reus).
Walcott can go in this scenario. Wilshere can stay as a Ramsey backup. We need to bin Flamini, Arteta can stay in the role Rosicky is in - will be a mature head in the dressing room and will play only when needed. All of this means that we need at least someone to compete with Coq, as i doubt we can find a clear upgrade on him.
Ospina is staying as no1, im sure of it and fine with it. Just bin Szczesny and get a mature backup.
We're fine in defence, as i dont believe we have any interest in buying a CB after buying Gabriel. Mertesacker sure aint going anywhere. I would prefer Gibbs out, Gaya in scenario, but i doubt he is interested in us. He would surely want to be a starter and Valencia is fine, until a spot in Barcelona/Real Madrid opens up.
So, our most pressing issue this summer is getting an RW who can produce similar numbers to Alexis, then a decent competition for Coq and then a mature replacement from Szczesny.
