BREAKING: Jose Mourinho SACKED by Man Utd
The Red Devils were humbled by Liverpool on Sunday as they were beaten 3-1 by their fiercest rivals at Anfield.
And United have decided that result was the final straw and have partied company with the Portuguese.
A club statement read: "Manchester United announces that manager Jose Mourinho has left the club with immediate effect.
"The club would like to thank Jose for his work during his time at Manchester United and to wish him success in the future.
"A new caretaker manager will be appointed until the end of the current season, while the club conducts a thorough recruitment process for a new, full-time manager."
Mourinho spent two-and-a-half years in the Old Trafford dugout and won the EFL Cup and the Europa League in the 2016-17 season.
But the defeat at Liverpool left the Red Devils 19 points off their fiercest rivals who currently top the Premier League.
Finishing in the top four is a minimum requirement for United this term and they are already 11 points adrift.
Mourinho was a vocal critic of United's transfer policy after he failed to land any of his prime defensive targets last summer.
He was desperate to sign a big-name centre-half with Toby Alderweireld and Harry Maguire among the names on his shortlist.
And United have now grown tired - pulling the trigger on Mourinho and announcing they will appoint a caretaker boss until the end of the season.
Sky Sports reports that Manchester United will officially appoint a temporary manager until the season within the next 48 hours.
Meanwhile, Carrick and Kieran McKenna will reportedly continue to take training - with the former acting as interim boss - as the search for manager goes on.
Club statement said that "a new caretaker manager will be appointed until the end of the current season, while the club conducts a thorough recruitment process for a new, full-time manager".
It is now reported that Zinedine Zidane becomes the hottest favourites to replace the sacked Jose Mourinho.
Former Real Madrid manager Zidane has been strongly linked with United in 2018, with talkSPORT's French journalist Julien Laurens saying: "He would be tempted – I think he loves the idea."
