Good points. I don't think no.10 is likely to be his best position. It's a loss to have him not getting in and around the box for sure. But I've seen him play a lot in defence for Hearts and right back did used to seem like his speciality, when he was up against poorer opposition. I reckon right wing back might be his ultimate position, but how often are we likely to play that system?
Pre-season will be key to sort this conundrum out finally. If he has the ability to be a right back starter in the PL, then that means our squad has a right back too many. We should go with two in the squad with Coxe as third choice (if he doesn't get a loan)
