They are now in the process of looking for a manager to take over from next season.Speaking to a fans' forum, Murtough was asked about Manchester United's process of appointing a new manager. He explained:"Out of respect for Ole, we did not approach other managers before he left. Our plan then was to appoint an experienced interim manager and Ralf was our clear first choice. He's someone I have admired for a long time, and we're delighted he's here."By bringing in Ralf, we can now take time to run a thorough process for our next permanent manager. Recruiting a manager is one of the most important decisions a football club makes so we want to do it in a careful and considered fashion."MUFC Scoop@MUFCScoopJohn Murtough: “He [Solskjaer] re-set the club’s culture and reshaped the squad, leaving us in a stronger position today than when he returned in 2018.” #MUFC7:29 AM · Dec 23, 202156540John Murtough: “He [Solskjaer] re-set the club’s culture and reshaped the squad, leaving us in a stronger position today than when he returned in 2018.” #MUFCRalf Rangnick has steadied the ship significantly since his appointment and is unbeaten in the three matches he's taken over so far."We're all disappointed at Ole's departure" - Murtough on Manchester United's appointment of Rangnick following Solskjaer's exitRangnick has had a successful beginning to his Manchester United career so farMurtough also went into detail about Ole Gunnar Solskjaer's sacking and the process that Manchester United went through to appoint Ralf Rangnick.He told the fans' forum:"There were grounds for confidence that we were going to continue building on the progress we saw in the prior two seasons.
