Following Jose Mourinho's sacking on Tuesday, Manchester United accidentally confirmed that Ole Gunnar Solskjær would be appointed as the new caretaker manager.Mourinho was sacked following months of scrutiny after a seemingly never-ending run of horrible results and feuds with players and the administration. The Red Devils' 3-1 defeat to bitter rivals Liverpool proved to be the last straw for the club, ultimately leading to the sack.The announcement was made in a club statement released on Tuesday. The statement read, "Manchester United announces that manager Jose Mourinho has left the club with immediate effect.""We would like to thank him for his work during his time at Manchester United and 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."The 55-year-old manager won the Europa League, the EFL Cup and the Community Shield during his time at Old Trafford.Manchester United has announced that Jose Mourinho has left the Club. We would like to thank him for his work during his time at Manchester United and wish him success in the future. #MUFC— Manchester United (@ManUtd) December 18, 2018Meanwhile, Solskjær's appointment appeared to be confirmed when Manchester United posted a throwback video with a description.The description read, "Solskjaer becomes our interim manager, 20 seasons after clinching the Treble with THAT goal at Camp Nou..."Manchester United have inadvertently announced Ole Gunnar Solskjær as the club's new interim manager.

That already feels like progress after the misery of 2018. He will restore courage, joy and spirit to United’s play.
