"All solid in midfield"
You've got one who might do well (Xhaka) and a very good one (Cazorla), who is now injured and aging. I don't think Ramsey, who is no longer the same player, should be mentioned as an option. Wilshere will be injured, and with him it's still a case of him just not being very good. Not a serious option.
Elneny and Coquelin are, at best, decent. I'm also not a fan of the idea of any of those two, starting together with Xhaka in midfield.
This is nowhere near good enough.
