Surely now it would make sense for them to make the announcement immediately before the Norwich game, rather than after? He can do his press conference and confirmation could be made any time on Friday or Saturday.
I want him out, but it would be better all round to avoid further protests and let those fans who want at least to show some appreciation for his efforts, if nothing else, do so, after the game. I don't want things to resort to Martinez having to just slink off from the club like a thief in the night. He is going, and there is simply no need to make things any more unpleasant for him than is necessary.
If they are not going to take that route, then I would expect things to be clarified by the Monday at the absolute, total, latest.
