At this point I find it comical to read that the main reason to appoint Solskjaer is emotionality, old memories and all that.

He's got more points than anyone else since he came (including 10 points more than Pochettino), taking over in December a depressed team that he didn't build, that he didn't know deeply, implementing changes in the way we played. And still made us competitive in the league, FA Cup and CL with all the limitations we have, and suffering a plague of injuries by the way.
The man has brought energy, ambition, he's been flexible tactically and we've seen glimpses of brilliance after dark times. He has revalued players who were totally lost for the cause, and we've destroyed under him all kind of historic records. With these cards on the table any manager would be the favourite to get the job regardless of being a club legend or not.
Pretending this is about emotions and blind faith is nothing more than a bad joke. If anything, logic suggest us to appoint the one with +10 points and not the one with -10, even more when Solskjaer is doing it here already which is yet to see with any other candidate. Also let's not forget that Ole has surely identified all our flaws and how to fix them, while any other manager will take time to analyze the team from zero. So again based on logic there isn't a better candidate than Solskjaer to make us competitive from the first game of next season.
Then, things like hunger, bravery and desire to be here should be taken into account. I feel that Solskjaer wants this chance badly and is determined to succeed. He's fearless about it and you feel the man is living a dream. He's well surrounded too, knows every corner of the club and its entourage and is respected by everyone, an authorized voice. That's another clear advantage.
With Pochettino I don't know what he's thinking, but to me he seems reluctant at the moment to leave his comfort zone to face a challenge like this one, probably more after seeing two legends of the game to fail here miserably in the last years. So if I'm right and he's doubtful about coming, we better leave him there meeting the season expectations. Probably when Ole leaves in 2025 Pochettino will be there still and yet to win a trophy.
