So in came Rangnick while United embarked on a "thorough" process to identify a long-term appointment. ESPN revealed earlier this season that one player admitted to teammates that he "had to Google" the 63-year-old
German, who did little to impress a sceptical squad by hiring unknown coaches Chris Armas and Euan Sharp because he was familiar with them from his time working within the Red Bull franchise at Salzburg and Leipzig.
Sources have said that Rangnick was compromised by both Carrick and Kieran McKenna deciding to leave their coaching roles and then saw three potential appointments ruled out by unavailability or Brexit red tape, but Armas and Sharp were, nonetheless, his appointments.
Rangnick also set alarm bells ringing within the club when he was warned that managing United would lead to unprecedented scrutiny of his results and decision-making in the media and among supporters.
"Ralf just smiled and said, 'Don't worry, I moved to a big club before when I left Hoffenheim for Schalke so I know what to expect,'" a source told ESPN. "It's fair to say that he had no idea what to expect."
By January, sources told ESPN that Ronaldo had made it clear to the club that he would not stay at United if Rangnick was given the job on a permanent basis and the
Portugal forward was not the only player unimpressed by the interim boss or his coaches, with
ESPN reporting that former FC Toronto coach Armas had been nicknamed Ted Lasso -- after the fictional, hapless American coach parachuted in to manage fictional side AFC Richmond in the hit Apple+ comedy show -- by some within the squad.
