Former Bayern Munich striker Giovane Elber has hailed the European form of Iker Casillas.
Elber is amazed by the Real captain's ability to be up for Champions League games, while being forced to sit out Liga action.
"What makes Iker so awesome is that it's not easy to play only in the Champions League and Copa.
"You have to play the Liga to become fit. I say that without Casillas on the field, Madrid would not have passed the tie against Borussia Dortmund."
