Ole Gunnar Solskjaer turned down the chance to make changes to his Manchester United backroom staff despite players voicing their concerns over coaching methods and tactical implementation.
Man Utd confirmed on Sunday morning that Solskjaer had been relieved of his duties as manager, with Michael Carrick taking over while the club searches for a new interim boss.
The final straw for Solskjaer was a 4-1 defeat at the hands of newly promoted Watford on Saturday, despite his assertions post-match that United had at least played well in the second half.
Bruno Fernandes and David de Gea stuck up for Solskjaer following the defeat at Watford, but ESPN report that United's senior players had already lost their faith in Solskjaer following their 5-0 loss at home to Liverpool last month.
Players did not believe that Solskjaer and his backroom staff were good enough to elevate the team and compete at the top level, while training sessions had been described by a source as 'too British'.
Solskjaer was assisted by Carrick, Kieran McKenna and Mike Phelan, while specialist set piece coach Eric Ramsay joined in the summer to some fanfare - even though set piece coaches are commonplace in football now.
The United hierarchy were aware of the limitations of the coaching setup and repeatedly offered Solskjaer the chance to make changes to it, but the Norwegian believed that his backroom team were 'world class'.
Carrick's first game in charge of Man Utd comes on Tuesday in the UEFA Champions League away at Villarreal.
