This was what I was suggesting, sorry if it wasn't clear.
Something like
Jags -- Stones -- Distin
Coleman -- McCarthy -- Baines
Mirallas Barkley
Naismith
Lukaku
Honestly, not very different from today, except for Stones playing Barry's role (but he'd obviously play it more like a CB than a DM, hence where I put him).
Basically, we have to drop Barry and Barkley doesn't really seem ready to fill in back there. So that basically leaves us with the options of a) throwing in Gibson (if he's fit) b) playing Barkley/Osman there and hoping that they figure out how to deal with City's counter c) just playing McCarthy back there and praying he has an earth shattering performance or d) my plan.
