Julian Nagelsmann and his staff are pulling out all the stops in order to keep spies away from camp ahead of Friday's Euro 2024 quarter-final against Spain.
Germany have been one of the best performing teams in this summer's competition so far, recording victories over Scotland, Hungary and Denmark.
Spain, meanwhile, have won all four of their matches to date, conceding just one goal as the likes of Nico Williams, Lamine Yamal and Fabian Ruiz shine on the biggest stage.
The hosts will have to be at their very best to beat Luis de la Fuente's side, who are one the favourites to lift Euro 2024.

And it appears Germany are going the extra mile to keep their tactics under wraps, according to BILD, who claim staff are playing loud music on their mobile phones to prevent any spies or passers-by from listening.
In fact, staff were heard playing the title song from the German children's series 'Benjamin Blümchen' as two BILD reporters walked past on Wednesday morning.
Nagelsmann has history when it comes to dealing with spies. Last year, when he was at Bayern Munich, detailed information about the team's tactics were published in the media.
Pictures of Nagelsmann's new strategy with the Bundesliga side, featuring passing and running routines, was available to read.
The 36-year-old was understandably furious by the leaks. “We have a snitch in the locker room. This bothers me a lot," he told reporters.
"Whoever is doing this is hurting every single one of us. I don’t understand his motivation, except helping the opponent.
"Moles are an endangered species and their search is difficult, but I don't know if that person will be able to look in the mirror everyday."
Nagelsmann added: "I try to find out what the reason is. For me it is always important to be able to look in the mirror at night, to treat my players and my fellow coaches well. I hope that this person can't look in the mirror because it's not fair."
Germany will face Spain on Friday afternoon in what is expected to be a thrilling encounter at Stuttgart's MHPArena.
