I think you're exaggerating and not taking context into consideration at all. It was Ipswich, a team everyone knows will go down, playing an insanely high line against which Liverpool took about 55 mins before even registering a shot on target. Once they got the opening goal they were more fluid, sure, but they were also particularly bad (much moreso than Utd, against a much, much weaker side) up until then. Utd had a good performance against a middle-tableish team, with a bit of a dip in second half (but nothing as bad as Liverpool).
I can see the trend
@Tyrion mentioned becoming a thing, Dutch posters wanting to appear more knowledgeable than others on the manager (which you obviously are) but saying he's a better fit for Liverpool than Ten Hag was for Utd is strange and doesn't really mean anything. We'll see in time whether that's the case.
