This is the new special coal and steel Borussia Dortmund shirt 2022/23, a special edition strip worn by German giants Borussia Dortmund over the weekend against Hertha Berlin. The colours of the kit pay tribute to Dortmund’s past as a mining and steel town- the shirt is all black while the lettering and numbers of the jersey have a steel-like feature to them, as can be seen in the pics below.
Dortmund won the game against Hertha Berlin 4-1, with Adeyemi, Malen, Reus and Brandt scoring for BVB.
