If it is in fact true that the club would only let him go to the championship and their were takers in L1.
Whos decision? Well presume it was nothing to do with Cooper as he has refused to use him and had several chances already.
I mean it won’t be long till he’s 20 and he’s STILL not made a competitive start or meaningful substitute appearance. He should have several U21 caps to his name by now, regardless of his long term injury.
