Last sentence first: Of course they should. I've posted that I think their public campaign against Ten Hag is unprofessional and I actually called it indecent. I was also baffled how eagerly and unquestioningly kicker let themselves be used as mouthpieces for the Leverkusen management.
They also clearly must have made major mistakes in either vetting or negotiating in the hiring. They, as opposed to the German public, must have known his insistence to be involved in hirings and even the problematic way of involving his own agent from his time at United.
Notwithstanding that, they are well within their rights to sack him as early as they can if the clashes turned out so virulent.
Second sentence, obviously I don't know what he was led to believe. But here is what I posted about Leverkusen in May

I'm not an insider, if I knew it would happen anyone should know, let alone Ten Hag.
Now to the first point: of course Ten Hag's lack of success at Utd will have been registered in Germany.
But, and this is where the "world revolves" point comes in: what do you think the outside perception of United's last 10 years is abroad, from the outside?
Do you actually think the German casual football fan follows the minutiae, and puts the blame on every single individual we hire, like we do?
Do you think the German public goes,
"Oh, Moyes failed, didn't have the stature.
Angel Di Maria, coward.
Martial, lazy bum.
Van Gaal failed, over the hill boring dinosaur.
Schweinsteiger, completely over it.
Oh, now Mourinho is sacked, terrible manager.
Pogba, fraud, bad attitude
Mkhitaryan, only could shine in a farmer's league.
Lukaku, donkey.
Alexis Sanchez, lazy, fraud.
Solksjaer, just a PE teacher!
Sancho, overrated fraud.
Ten Hag, nothing but a bald fraud, horrible hiring.
You think they see us hiring manager after manager, and big money transfer after big money transfer, and register every one of these managers' and players' reputation as destroyed?
Nope, they register merely episodes of a club that is struggling. The reputation that is affected is mainly ours, not so much that of the people that come to our club and fail. Because all those people have careers apart from their failures at Utd, and these parts of their careers have also been registered.
It's only us who don't see the forest for the trees.
