Barcelona midfielder Yaya Toure admitted he felt humiliated at Real Madrid on Wednesday night.
Reflecting on the 4-1 defeat, Toure said: "Among many emotions, I felt humiliation and ridicule.
"I had never seen (coach Frank) Rijkaard so angry after a game. It was the first time I had seen him like that."
He added: "Mental focus isn't everything, but we failed to show on the field what we were capable of."
