Following a 2-1 victory against a team from Kazakhstan in the Champions League, the Borussia Dortmund delegation immediately departed Baku’s Sabah FK stadium without showering. The team chose to travel directly to their hotel spa instead. According to the German team's coach, they were explicitly advised against using the stadium’s showering facilities. The concern stemmed from fears about a bacterial presence in the stadium's water system. This precautionary measure was taken to avoid potential health issues for the players. The team prioritized hygiene and opted for the controlled environment of their hotel to maintain player wellness after the match in Baku. No further details regarding the specific bacteria were immediately released.
