Grant has lost the players confidence, clearly. He really should not have accepted them holding a meeting over his, should have demanded they attend now, threatened with fines and what not. At least then the players could respect his discipline. But instead, he just meekly accepts it, and now the players know they can get what they want. That spells trouble, unless someone in the group of players, i.e. John Terry is holding the utmost respect of the players and manages to keep them in order himself. I do think he'd be able to do this, but it is really a manager's job.
By the end of the season, JT is going to more qualified to manage a football club than Grant ever has!
