Real Madrid goalkeeper Iker Casillas believes it was the wrong decision to send Alvaro Arbeloa off during the match with Manchester City.
The Spanish full-back was given his second yellow card for a pull on Sergio Aguero's shirt in the second half at the Etihad Stadium.
But Los Blancos' captain has admitted that he thought it was an 'embarrassing decision'.
“We were embarrassed when the referee showed a red card,” he told Canal plus. “The referee definitely hurt us with that decision.
“It was a tough game, but the important thing from tonight is that we have qualified.”
