i'm with you on all counts - i think as a 5th/6th choice attacker hes fine, however i also think giving that spot to someone who could have a higher ceiling than Gil also makes sense (not priority by any means).I think most fans are pleasantly surprised with GLC whereas Gil is pretty much what we expected.
Having said that I'm happy with an 'ok' winger. A squad-level player to fill some gaps. If he even gets to average PL level he would already justify the swap with Lamela.
Ideally we dont have him leaving on a free given what we spent on him and its unlikely he signs again being that far down the pecking order.
