#NoToRacism

Schalke has apologized for its fans’ racist abuse of Borussia Dortmund youth player Youssoufa Moukoko during a match between the rival clubs’ under-19 sides on Sunday.

“Derby emotions aside, we completely condemn and oppose such insults,” Schalke said on Twitter.

In a tweet with the hashtag “NoToRacism,” the club said its supporter relations department “will take the necessary measures.”

Some Schalke fans can be heard abusing the 15-year-old striker on video after he scored his third goal from distance against their side in the 63rd minute.
