I am not sure the fans will be particularly sympathetic towards Glasner after this.
Parish in my opinion is playing the game, perhaps saying to Glasner, if you want to leave then quit because you are not getting any compensation.
With regard to transfers, as Lanzo wrote earlier why the hell would we be looking at transfers for a manager who has only 5 months left. It makes no sense. In fact, telling a club, as a manager, that you are leaving makes no sense at all.
People are comparing this to Klopp doing the same thing however there is a massive difference. Klopp wanted to step back from football. Glasner wants to step back from Palace, a point he has made abundantly clear, blaming the Board for his decision. Ok some would say this is reasonable, however he has now done the same thing 3 times in 6 years. Leopards, spots etc?
I still expect him to go quickly, I just think in the background Parish is getting his ducks in a row to make it happen.
Personally I agree with those who say put him on gardening leave, put Paddy in charge, get a couple of loans in and keep any money for the new manager. Move on quickly.
