He might be able to coach a team, but managing is a different ball game. The latter involves having the ability to coax the best out of the players at your disposal. Be a friend, a confidante, an ally to your players. Good managers can bring the best out of their players simply by standing shoulder-to-shoulder with them. Maureen throws his players under the bus on such a regular basis he should wear a bloody great big cloak with a huge hood, and carry a long-handled scythe and call himself the grim reaper.
Look at the affection many clubs have for former managers: supporters that still sing their names although they may well be long dead and buried.
I would imagine many fans of the clubs that Maureen has poisoned along the way are wishing he himself was dead and buried.
