Unfortunately I think IB will be on his way.
As I like the guy, and the way he tries to get the team to play good football, my immediate thoughts were doom laden. However no one had heard of him, before he became manager, so who's to say the brothers will not have another good un lined up, if IB goes to pastures new.
My big fear is that the players might have become unsettled if they know IB is on his way and so, underperform.
