That’s such a lazy question, reminiscent of Priti Patel asking if others have better options and, like the other user said, especially difficult to remember who was available at the time.
I do seem to remember Nagelsmann and Rose were available at the time. But frankly you could have thrown a dart at a board with pictures of available managers and landed on a better option.
Again, I have no idea who was available at the time or what they were doing. The type of manager I would have liked would have been in the progressive, modern manager mould. So someone of ETH's ilk. Maybe someome like Marco Rose or Nagelsmann, though I'm not sure what they were doing at the time.
It's been sickening watching the likes of Liverpool and City play really progressive brands of successful football, while we have gone for managers with no real style whatsoever. LvG was the closest we got to a manager who had a clear tactical identity, but that didn't work out. Funnily enough, he allegedly wanted Mane and VVD while both were at Southampton, so interesting had he gotten both.
Nagelsmann was 31 years old and in his first managing job at Hoffenheim at that point, I don't think you wanted him that badly at the time. Rose also pretty much had his first managing job.
My point is that it's very easy to look back and criticize decision made in the past, and I don't really like people who criticize and don't offer any options or opinions themselves other than the criticism.
The dressing room was extremely toxic and Ole as interim manager was what the club needed at the time. It is also understandable that he was given a full time contract based on the massive interim success and amazing atmosphere when the decision was made.
Some quotes from Wikipedia:
"Solskjær's first match was against his former club, Cardiff City, on 22 December 2018, with United finishing as 5–1 winners.
This was the first time United had scored five or more goals in a Premier League game since a 5–5 draw with West Bromwich Albion in Ferguson's final game in charge before his retirement in May 2013. Victories in his next four league games
made Solskjær the first Manchester United manager to win his first five league games in charge since Sir Matt Busby in 1946."
"Solskjær's successful first full month as Manchester United manager resulted in him being named as the Premier League Manager of the Month for January 2019, during which time his team earned 10 points from a possible 12 in the league,
making him the first Manchester United manager to win the award since Ferguson in October 2012."
"Two consecutive away wins in the league against Leicester City and Fulham
gave United six consecutive away victories in all competitions for the first time since May 2009, and sent them into the top four of the league table."
"Having picked up 25 points since taking over,
Solskjær earned more points than any other manager has managed in his first nine games in charge of a single club in the Premier League."
"A 3–1 win at Crystal Palace on 28 February 2019
set a club record of eight consecutive away victories in all competitions."
It's time to look forward. As we all know, there are a lot of rotten apples in the squad. We have now signed an interesting up and coming manager and the summer transfer window will be extremely important.
