This is a joint action of the German Football League (DFL) and the clubs. Head coach Gerardo Seoane spoke about developments in Eastern Europe at the pre-match press conference, clearly affected by the situation: "Of course, it's a subject of discussion in the dressing room for all the players and coaches plus the staff. Seeing images like that is a great shock to all of us. We condemn war in any form and are convinced that everything should be done to get back to the diplomatic path to find a solution without war."
Moreover, Bayer 04 has decided to show our feelings towards the war in Eastern Europe in and around the game. A number of entertainment elements will be dropped and no carnival music will be played. The club asks for your understanding.
Today's match against Arminia Bielefeld will be refereed by Martin Petersen. The 36-year-old was in charge of his first game in the Bundesliga in 2017.

The most recent Leverkusen match under Petersen was on 13 December 2020 and that ended in a 4-1 home win against TSG Hoffenheim.
The match official from Stuttgart will be assisted by Alexander Sather and Robert Kempter, Felix Zwayer is the VAR referee. Have a good game.
