Thomas Tuchel singled out three of Bayern Munich's star players for criticism during the team's punishing pre-season preparations, according to reports in Germany.
The head coach, who joined the Bundesliga champions in April just a month and a half before the end of the season, has been vocal about who was up to his exacting standards during the very first session at the camp in Tegernsee, in the Bavarian Alps.
Bayern won a record-extending league title under the former Chelsea manager, but by some measures fell short of the club's extremely high standards after the Champions League and the German Cup in a slightly chaotic end to the season.
