In fairness Milwall are a side who will be in and around the play off picture so it's not as if he's going back to Sunderland or something.
I'm not sure they will, they've lost Kieftenbeld and Jed Wallace, which were two of their key players. They've signed Flemming from Fortuna Sittard, who is a handy player, but I'm not sure they'll do as well this season. I wasn't particularly impressed with them when they played us.
