Sir Alex Ferguson is retiring as manager of Manchester United, the club has confirmed.
The manager, who has been at the club for 26 years, said in a statement: "The decision to retire is one that I have thought a great deal about and one that I have not taken lightly. It is the right time.
"It was important to me to leave an organisation in the strongest possible shape and I believe I have done so."
The club has not not immediately announced a successor.
The Scotsman secured his 13th Premier League title with Manchester United two weeks ago and is the most successful manager in British football history.
Ferguson, 71, will stay at the club as a director and an ambassador, but now has just two games left with the famous club.
"With these activities, along with my many other interests, I am looking forward to the future," Ferguson said.
"I must pay tribute to my family, their love and support has been essential."My wife Cathy has been the key figure throughout my career."
Former FA chief executive Mark Palios told Sky News that Ferguson's achievements were unrivalled and said they "would never be repeated again".
