If he doesn't go tomorrow, is it going to be too late?
Are we really likely to improve this season with him in charge? No...I really can't see it.
Are we really going to attract decent players in January with him in charge, and with us looking likely to be in a relegation fight? Unlikely.
Would we be able to get a better manager in if we got rid of him after January? Doubt it.
If he goes in January or just before, and we start the window without a manager - what is the impact on our transfer window dealings? Not positive.
We need him gone this weekend.
