Per the report, several players believe that Nagelsmann is more suited to club management and is too demanding. There is not said to be a lack of faith in the manager, but they would like him to simplify his ideas, due to the condensed nature of training at international level.
Nagelsmann has also played several players out of position - for example, Kai Havertz has been fielded as a left-back - and is said to place great faith in video sessions, while he also stops training to point out mistakes. Overall, it is said to have overwhelmed the Germany squad.
