But that is the problem - he might have beat expectations that were specifically lowered for him. If you take a big picture of each season - no way he beat expectations of a United manager. At best, he achieved the very minimum of expectations and even that is questionable due to total absence of trophies (which used to be an extremely important measure here until a portion of a fanbase moved the goalposts for Ole and started advertising 2nd and 3rd place finishes as some great achievement).
2018-2019 - great run and night in Paris, but started 6th and finished 6th and handily beat by Barca. Overall - ok record for caretaker, but not much more.
2019-2020 - for any United manager the very minimum expectation would be top-4 and good run in cups. He barely achieved it - we snatched top-4 in the last day, being 33 points from top, 15 points off second and level with 4th. And this 3rd place finish has continuously been mentioned in defense of Ole as if it was a comfortable top-4 finish. It wasn't. FA Cup and Europa we made semis which is ok but we had easy runs in both of them - beat AZ, Partisan, Astana, LASK, Brugge and Copenhagen in EL and Wolves, Tranmere, Derby and Norwich in FA Cup. Beat by first serious opponents in both competitions. Overall, minimum expectations barely achieved. Anything just a bit worse would be a disappointing season.
2020-2021 - again, for any United manager the very minimum expectation would be to improve on points and be not far away from the title plus win a cup or have a good CL run. In the League I would say we achieved minimum expectation (although influenced by the dire state of most of the rivals). Crashed out of CL group, and did not win any cups, although you can argue made EL final and beat some good teams. Overall - again, I would say minimum expectations barely achieved at best.
2021-2022 - crashed.
Yes, small teams do not have CR7 and Sancho "problem", but they have the problem of having to overachieve on limited budget and limited player quality, which must be compensated by good coaching/tactics to get decent results. So far in his career, Ole has not shown anything suggesting he can do it. He always mostly relied on large budgets and individual player quality. But will be very interesting if he can reinvent himself in a smaller club. I hope so, I do not enjoy people being unsuccessful and stressed for all my anti-Ole rhetoric
But he would be a huge risk for a small club.
