German football club Schalke has issued an apology after its fans allegedly directed racial slurs at Borussia Dortmund forward Youssoufa Moukoko during an under-19s match between the two teams on Sunday.

The 15-year-old player netted a hat-trick to help his side secure a 3-2 win over their main rivals. It was as Moukoko was celebrating his third goal that the home supporters allegedly unleashed a string of racial profanities at him.
