The footballers from the Borussia Dortmund ball game club sounded as if they had to look in the mirror to see whether their lips were still hanging properly. “That was a complete slap in the face,” said Julian Brandt as he stood in front of the reporters in the catacombs after the 4-1 defeat at RB Leipzig. His coach Edin Terzic was also “frustrated” and “angry” – about the defeat itself, which had barely been hinted at at this height after Jadon Sancho’s beautiful opening goal. But above all about this: “We not only lost the game, but also our game from the 20th minute onwards,” said Terzic aptly. Four days before the first leg of the Champions League semi-final against Paris Saint-Germain, that didn’t correspond to BVB’s desired scenario.
