Presume the "known" midfielder was going to be assistant and were either looking for a similar type of player (maybe a different position) or now looking to approach other types of candidate and it can wait until the window is closed.
Don't care, get rid if not needed. I'm sure his definitely legitimate Leeds United move will materialize.
Our fullbacks have a big shitebag problem so you canny play him there as he's even more feart.
