Frankfurt’s sporting director Fredi Bobic said the entire team wanted to show it was “together against all forms of racism” amid widespread protests around the world, sparked by the death of George Floyd.
The team’s regular shirt sponsor had the hashtag #blacklivesmatter emblazoned across the front, whilst Bayern players once again wore t-shirts supporting the cause during the warmup.
“Eintracht Frankfurt’s history is shaped by open-mindedness and international understanding. These attributes are firmly anchored in the Eintracht DNA,” said Frankfurt board member Axel Hellmann.
“Racism, xenophobia, antisemitism and homophobia have no place within the Eintracht family and must have no place in a liberal society.”
In addition to its warmup jerseys, Bayern displayed its #RedsAgainstRacism initiative on advertising boards around the stadium and on corner flags.
The host eventually won the game 2-1 to reach the German Cup final for the third consecutive year.
“This evening at the Allianz Arena, FC Bayern will be making another clear statement against all forms of racism, discrimination, intolerance and violence,” read a post on its official Twitter account.
Bayern’s players also wore black armbands in a match against Bayer Leverkusen at the weekend to support the movement.
A number of other sporting figures across the world have stood in solidarity with those protesting racial injustice.
Borussia Dortmund star Jadon Sancho displayed a “Justice for George Floyd” top after scoring in the Bundesliga, as did his teammate Achraf Hakimi.
Manchester City forward Raheem Sterling also said he supported demonstrators and called for better representation in positions of authority in the game.
