Of course he should go, he has shown no quality that makes me think he should be trusted with next season's challenges - recruit an entire squad, develop a game plan and motivate a squad. Clearly he is here to the end of the season - who would come in now, not knowing who will own the club or what league they will be on.
I don’t disagree with any of what you said. The sad reality is that he has a 20% win ratio overall and that is nowhere near good enough. On this basis we are on course to win 2 more games this season.
Overall we have 29 points from 36 games. That is 0.81 points a game so based on this form throughout the season we are destined to pick up 8 points, thus finishing on 37 points which is at least ten point less than what we would need to stand any chance of survival.
