I don't know who changed it - it wasn't me - but how does that indicate whoever-it-was being in the club's pocket?
I like the way the club are leaving it until the very end of the day to do it - will be a nice surprise for many when they wake up.
My guess, and I stress it is only a guess, is that Bloom hasn't been able to find someone suitable to replace him. If he has to pay Hyypia off, he'll be unlikely to want to also have to buy another manager out of an existing contract.
