If he had any class, or even just for the sake of cold expediency, he would apologise today for his outburst last week. He doesn't need to go the full 'insincere politician', just a quick 'It was heat of the moment, I was in the wrong (even if only to air things in public), and I won't do it again. No further questions, back to work'.
That would allow all parties to cooperate beneficially until the end of the season, and also allow the media s***-stirring spotlight to move back to its natural hunting grounds at Spurs, West Ham, Man United etc. The simple act of not falling apart internally whilst others do is a big part of why we stay up with no drama every year. If Glasner can't toe that line then he really will have to go.
The ball is in his court as far as I am concerned.
