Manchester United have "acted unprofessionally" over the manner in which they parted company with manager David Moyes, who they offered a six year deal to in 2013.
That is the opinion of the League Managers Association who, through CEO Richard Bevan, released a statement saying: "David Moyes is one of the most talented, knowledgeable and dedicated managers in British football. It is sad to see the end of David's tenure at United being handled in an unprofessional manner."
Moyes spoke of his pride at working for one of the most renowned and revered football clubs in the world, claiming the scale of the job was "immense".
"To have been appointed as manager of Manchester United, one of the biggest football clubs in the world, was and remains something of which I will always be incredibly proud. The scale of the manager's job at United is immense, but I have never stepped away from hard work and the same applies to my coaching staff. I thank them for their dedication and loyalty throughout the last season."
On under-performing, he said: "During this period of transition, performances and results have not been what Manchester United and its fans are used to or expect, and I both understand and share their frustration."
On his next move, Moyes added: "I have always believed that a manager never stops learning during his career and I know I will take invaluable experience from my time as United's manager.
"I remain proud to have led the team to the quarter finals of this year's Champions League and I remain grateful to Sir Alex Ferguson for believing in my ability and giving me the chance to manage Manchester United."
