I think it’s harsh to rule him out of FT altogether on the back of one bad move. It sounds like he was adamant on sticking to a philosophy despite it never working, perhaps given a full summer transfer window and time to bed in it might work better for him in the future.
A fit Grimshaw would be ideal to cover RB and CM should Wilson be injured or need to cover for a CB. I don’t think we should have much faith in Corr staying fit given his record so far.
Why do you struggle to believe it? Numerous people saw it, including myself. The bus hadn’t left yet, so it’s not as if it stopped and let them off to go and do what they did.
