Everyone can name the cue that starts a press; the collapse almost always happens with the player who was supposed to follow it.
A press does not fail on the trigger, it fails on the second man
Back pass to the weaker foot. Heavy touch. A defender receiving square with his back to the pitch. The list of triggers is common property now, taught at every level, and if you stopped ten professionals in a corridor all ten would give you roughly the same answers.
Which is why I have stopped finding the trigger interesting. Teams do not concede because a striker failed to recognise a cue. They concede because he recognised it, went, and the man behind him did not.
Picture the sequence. The forward reads the pass and sprints to cut the return to the goalkeeper. The centre back now has one option, a pass into the pivot, and the whole press depends on your midfielder being on that pivot's shoulder at that instant. If he is a metre and a half off, the ball goes in, the pivot turns, and your first line is behind the ball with the pitch open. One player did his job perfectly and the outcome is worse than if he had done nothing at all.
That asymmetry is why pressing is so hard to install. It is not additive. Ninety per cent execution does not give you ninety per cent of the benefit, it gives you a structure that is exposed exactly where it committed, and a squad that quickly learns not to trust the trigger. After two or three of those, the striker stops going. Nobody says anything. The press quietly dies of disappointment.
The fix is boring and mostly about who leads. The second man has to react to his own teammate's movement rather than to the ball, which means he is watching a player behind him while the ball is in front of him, and that is a habit built in dull repetition rather than in match-realistic drills. The teams who are good at it have usually kept the same midfield spine together for years, which is another argument against rotating everything in sight.
If your press keeps breaking, film it from behind the goal and watch nobody. Ignore the ball, ignore the trigger, and follow the second man. He is where the answer is and he is almost never the one being blamed on the Monday.
