And sources have now said that several key players had become exasperated by the ability of Solskjaer and his coaches to make the team better, with
one source telling ESPN that the players regarded the training as "too British" and unsuited to the requirements of the modern game at the elite level.
Solskjaer's coaching team was made up of former United players including Michael Carrick and Mike Phelan, as well as Northern Irishman Kieran McKenna. Several other coaches had previously worked with Solskjaer at Cardiff City, where he was relegated from the Premier League, and in Norway with Molde. Solskjaer's coaching team remains at the club, with the manager the sole departure as things stand. The club hired a set piece coach, Eric Ramsay, in the summer.
Sources have said that the United hierarchy had become aware of the concerns over the quality of the coaching team and "offered Solskjaer every level of support and told him he could have whatever he needed to put it right."
Executive vice-chairman Ed Woodward was told, however, that Solskjaer believed his coaches were world-class, forcing the club to back the manager's judgement.
Following Solskjaer's departure as manager, former United midfielder Carrick will take caretaker charge against
Villarreal in the Champions League on Tuesday.
