This comment from transfermarkt.de comes from a user who basically says he watches the training sessions, and calls the training is extremely lax and even the worst it's been since 10 years (which means even worse than under Kovac and Ancelotti). But he attributes it to the loss of quality teammates to train with due to all the injuries (although Tuchel's training might be causing injuries) and fear of having even more rather than Tuchel's approach to training being inherently simplistic/not good enough.

"Öfters" means "more often" in conventional German, but can mean "often" in southern German dialects. It could be that the user means the level of training fell this far only recently, otherwise he would have blamed Tuchel if it was bad even before the injury crisis. Or it was "more often" and he didn't watch the trainings that often at the start of the season.

I don't buy it though. Both Pep and Nagelsmann had massive injury crises, and neither allowed the standards to drop this far. Aren't there ways to make the level of training less dependent on the competition? If there are fewer quality options and a worse balance, why not try to compensate with more tactical meetings and analyses, for example? And how's it that clubs with worse individual quality manage to have better training sessions?

This explains a lot about the current level of play, and means Teflon Dumbass was lying all along about super-duper training sessions. He even managed to brainwash the players into not contradicting him or calling him out in interviews, even Müller.
