Don’t think he’s ready for the CM position personally. Especially with his tendency to lose focus and his lax passing under pressure (and even with little or no pressure). I think he probably gives us much more in the LB role, and depending on Bellerin’s form, it’s nice to have a decent option there. Compared to central midfield where we are trying to (or should be trying to) upgrade Xhaka, and if Ainsley isn’t nearly good enough to displace that limited piece of drudgery, he definitely won’t have much of a shot staking a claim versus Xhaka’s replacement.
