We have freed up quite a bit in wages this summer though with Danny Ward, Etheridge, Connolly, NML & Jazz out the door.
Callum is a pain in the arse player to the opposition, someone who can come on, rough them up and free up ralls, tomlin and the rest to create some chances. If 500K is being mooted then I'd much prefer to keep him, he would have been ideal to come on against reading and get us back in the game.
What do we know though.
