That’s very debatable. I know progress is rarely linear, but the prolonged spells of bad form and tendency to repeat the same mistakes again and again did cast doubt as to whether things would ever really improve.
There were undoubtedly occasions when it did look like progress was being made though. Most objective fans (yes there were some) thought that he definitely deserved another season following the strong finish to 19/20.
You’re right, but it doesn’t always happen that way. I’d wager that people remember Jose’s spectacular meltdown at Chelsea better than the previous season’s league title. Though maybe they wouldn’t if a similar thing hadn’t happened at United soon afterwards
If people took the same view as I did with Ole from the start, which was that he was not appointed for footballing reasons, it’s actually not that hard to conclude that he did a reasonable job.
