As per the report, the German national team hosts its training sessions at the Adidas site in Herzogenaurach, Bavaria and have put up two large fences covered with black tarpaulin to avoid their training sessions being seen by outsiders. The camp is also bordered by police on horse back to avoid any chance of the tactics being overheard.
In addition, Naglesmann's staff are also said to be playing loud music on their phones to prevent spies from listening in on their tactics.
