Lothar Matthaus has challenged head coach Joachim Low to get tough on his Germany stars and make it clear they cannot expect a place in the team based on past achievements.
The reigning champions endured a miserable World Cup in Russia, crashing out at the group stage with two defeats from three games.
Low called up three new faces in Thilo Kehrer, Kai Havertz and Nico Schulz for their first UEFA Nations League match against France on Thursday, although the majority of the squad comprises his usual favourites.
And former captain Matthaus says the coach must be prepared to drop any player who does not perform against Les Bleus or in the friendly with Peru in Sinsheim.
