I'd keep them all for now at least. Smith has said Edu is one for the future and who knows what Mcullochs is, so its good to have him here. I feel like i'm the only one who rates stevie smith but hes always looked good when hes came in for sasa, and in any case we'd get next to nothing for him. As for Broadfoot, right now hes our best defending option in that position - Whittakers great going forward but can be a defensive liability. Also wouldn't get a lot for him, but personally i wouldn't be gutted if he left
