for me, we have 3 distinct positions in our midfield now.
dm
cm
am
and the pecking order appears to be
dm: coq > ?
cm: cazorla > ramsey
am: ozil > wilshere?
everyone wants ramsey to play cm instead of cazorla. except wenger. if he wont play ramsey there, he wont play wilshere there ahead of ramsey.
coq is the first name on the team sheet, so given that, i can see why we might not want to spend 25m on schneiderlin, since he wouldnt really be first choice. we could do with a DM, somoene like coq, to provide rotation options. flamini and arteta arent good enough for that role in our current setup. but you can probably find a great alternative to coq for 10m or less this summer. no need to spend 25m on schneiderlin. though id gladly take him, obviously. we just dont have unlimited funds, so if that money is needed elsewhere, im fine spending less on a specialist DM
