Yeah, it's hard call time.
He hasn't stood up all year. Frankly, he's been downright awful. And that petulant bullsh*t in the goal square when Nicho took the shot is the last straw. When you're having a rotten day as captain, you have no right to do that sort of crap to a first year player who has shown far more than you this year.
If not with immediate effect, Green needs to be removed at the end of the year.
Note - yes I may be sounding a bit harsh, but if the club is willing to sack the coach, it needs to take a serious look at the playing group as well after that. Hold the administration to account, sure, but if there's a malaise in the playing group, it starts at the top. The playing group voted him as captain.
