The Dutchman was informed on Monday morning and leaves Old Trafford after two and a half years in charge with his final game proving to be the Premier League defeat to West Ham United on Sunday.
That result left the club 14th in the table, seven points off the Champions League qualification places, after just three league wins from nine games and only four in 14 in all competitions.
The club are now working on next steps with former striker Ruud van Nistelrooy, recruited in the offseason to work alongside Ten Hag, having been asked to take charge on an interim basis with the rest of the management staff remaining in position for now.
Ten Hag was retained as United manager in the summer after an end-of-season review following an eighth-place Premier League finish, the club’s lowest since 1990, and a FA Cup final victory over rivals Manchester City.
United triggered a one-year extension option in the 54-year-old’s contract at the start of July. His previous deal, which he signed when he was appointed in 2022, was due to expire in 2025.
