Atletico Madrid fans taunted Real Madrid skipper Iker Casillas during Saturday's 4-0 thrashing.

The goalkeeper was at fault for Tiago's opener.

"Iker, Iker, Iker…," mocked Atleti fans throughout the game.

The chant, which is heard week in, week out in the Bernabéu, was sarcastically directed at the keeper after his mistake which led to the goal.
