Would be a great loss but i've been expecting it for a while, suspect they aren't the first club to take an interest though, he may feel this is the right time to leave and take up a new challenge.
News we've been expecting for a while now. All the best to him, deserves his chance and hope he gets it right.
Hard boots to fill at United, will be interesting to see who gets the job. Joyce and of course Ole before were appointments made from within, suspect Joyce's replacement will come from the outside, in the long term anyway.
