I actually hope there is something in this.. He is the only player that I can't see has improved over his time with us, which might be due to his age, but it could also be down to a number of other factors.. and I suspect Emery has a good idea of whether he will eventually come good for us.
So far the fact is, we haven't suffered by selling or loaning players out. So I guess Emery knows what he is doing, and if he leaves, it means Emery/Monchi have spotted someone else that they feel they can get in, which can only be good news as far as I can see.
