Manchester United's angry players turned on each other in the aftermath of the humiliating defeat at Everton.
Manager Ole Gunnar Solskjaer kept his team in the dressing-room for more than half an hour after Sunday's 4-0 hammering at Goodison Park before publicly apologising to fans for the performance.
The players then pointed the finger at one another during a heated exchange, and raised voices could be heard from the corridor outside as they argued among themselves.
The inquest continued at a sombre Carrington training ground on Monday in another team meeting lasting an hour as the squad were subjected to a video analysis of their capitulation.
Solskjaer and his backroom staff were so infuriated with the performance that it is understood the team chef even gave players a piece of his mind.
The United manager and his assistant Mike Phelan held a recruitment meeting after training to discuss the changes needed this summer after a run of six defeats in eight games obliterated the mood of optimism around the club.
Insiders claimed that the situation is no better than when Jose Mourinho's reign began to unravel in September and October.
The fear among staff is that Solskjaer too will be brought down in time despite his popularity with supporters if there is not a complete overhaul of the squad.
