I disagree. A new manager will fit the requirements of the Chairman, same as the last manager. If the Chairman wants a younger, pacier side (for example) then it wouldnt make a jot of difference who the manager is.
As well as that, what is knee jerk about leaving when not getting games, getting loaned out and then having a bid accepted for you?
Corlukas 26 hardly over the hill. Still young in my book. The knee jerk part is him not waiting until the arrival of the new manager who, for all we know, may rate him higher than Walker. Unless, as you say, Levy has told him he won't be playing which I can't see personally.
