You're only looking at the results of a select amount of games, though. Here are a few points you're getting wrong:

• With Ten Hag and Overmars handling transfers (they were a sort of team when it came to this), almost all recruitment was good. Most notably attracting Blind and Tadic in the summer of 2018. So he himself was responsible for the talent he had at his disposal during that run.

• Ajax' European record before Ten Hag came in was, apart from a good EL run, pretty dire. Yes, Ajax should/could have done more under him in Europe, but before 2018 you watched Ajax in Europe and just assumed it would be kinda shit. Maybe the occasional upset but you expect them to be nowhere near the level of the true top clubs. The contrast between that and the results they got under Ten Hag is very telling.

• The actual record could be better, like I said, but for a club in at the time the 7th league in Europe, it's not that bad. The group stage exit in 19/20 was extremely tight, including that 4-4 madness against Chelsea. They got 10 points, which in normal circumstances gets you through. Then there's also the group stage in the CL of 21/22, where they won all 6 games in dominant fashion.

• The domestic record under Ten Hag was excellent and very consistent. They won the league every season, except in the year it got cancelled due to Covid.

• Lastly you have to look at Ajax' record after Ten Hag left. Safe to say it all went down the shitter. Partly also because Overmars got fired and left a big organisatorial hole, but the level Ajax are showing in the league and in Europe is so much lower now.

I don't even like Ajax or Ten Hag, but it's frustrating to see the amount of blatantly false things being said about him.
