German national team sporting director Rudi Völler says Antonio Rüdiger needs to show “class” and respect for others after he appeared to throw ice toward the referee during Real Madrid’s Copa del Rey loss to Barcelona.

Antonio Rüdiger has apologised for his sending off in Real Madrid's 3-2 Copa del Rey final defeat to Barcelona on Saturday, after he threw an object onto the pitch, and teammates had to stop him from confronting the referee.

Germany international Antonio Rüdiger could face a months-long ban after throwing an object at a referee. He was sent off alongside two Real Madrid teammates with the club at war with officials.
