Antonio Rüdiger needs to show "class" and respect for others, German national team sporting director Rudi Völler has said, after the defender appeared to throw ice toward the referee during Real Madrid's Copa del Rey loss to Barcelona.

Rüdiger shouted at the referee and seemed to throw a small bag of ice during extra time in Madrid's 3-2 loss to Barcelona on Saturday. Rüdiger has since apologized for his behavior but the incident prompted former Germany player Dietmar Hamann to call Sunday for the defender to be left out of Germany's squad for the Nations League final four in June.

After FC Barcelona won 3-2 against Real Madrid in the Copa del Rey final, in what was a wild 120 minutes of play, it's now time to think about what's next at both clubs, especially at Real Madrid, where there will be even more doubts about the future of Italian coach Carlo Ancelotti,
