Joachim Low has warned his Germany squad that anything less than a full-throttle performance against Netherlands will not be good enough.
Die Mannschaft cruised to a 3-0 victory over their north-western neighbours in a November friendly in Hamburg's Imtech Arena, and the 52-year-old has urged his players to repeat that dominant performance.
"Eighty per cent is not good enough," the former Fenerbahce boss screamed at his players after a misplaced pass in training, according to Kicker.
"You cannot do it when you only give 80%! You must play like you did in Hamburg!"
Germany and Netherlands kick off at 20:45CET on Wednesday, with die Mannschaft looking to build on their 1-0 victory over Portugal in their opening group game.
