Dortmund fine Karim Adeyemi after angry touchline reaction in Gladbach win

The night was overshadowed by disciplinary action against Karim Adeyemi following an angry reaction to his substitution.

Dortmund were quick out of the blocks at the Westfalenstadion and took the lead early on. Niklas Sule, back in the starting XI after two months out, delivered a measured cross to the far post and Julian Brandt volleyed calmly inside the upright. It was Brandt's latest decisive contribution in a strong run of form, as Dortmund continued an impressive unbeaten league streak at home.

The hosts pushed for a second goal before the break. Serhou Guirassy went close when a slight touch from Nico Elvedi denied him a clear header, while Gladbach goalkeeper Moritz Nicolas produced an excellent save to keep out Karim Adeyemi from close range. Gladbach briefly threatened before half-time when Florian Neuhaus broke into the area, but Sule recovered well to block his effort.

Dortmund controlled much of the second half and doubled their advantage late on. Substitute Maximilian Beier sealed the win after collecting Fabio Silva's pass and finishing confidently past Nicolas. The result marked a 13th successive home league win over Gladbach and kept Dortmund within touching distance of the teams above them.

However, attention quickly turned to Adeyemi, who reacted angrily after being substituted on the hour mark. Sporting director Sebastian Kehl confirmed the club would act.

"We will have to talk about the incident," Kehl said. "He will receive a fine because this is something we have discussed very intensively with the team."

Kehl also defended the decision. "The substitution was completely warranted. Karim didn't play well today. This kind of reaction is not acceptable, and Karim knows that."

Head coach Niko Kovac backed that stance. "He wasn't good today, which is why the substitution was justified," Kovac said.
