Deportivo La Coruna coach Gaizka Garitano was unhappy with the manner of defeat to Real Madrid.
Depor lost thanks to an injury time winner from Real captain Sergio Ramos.
Garitano remarked: "It was a nice, even game, we had a chance to win at the Bernabeu, but we gave away too many free-kicks. They're one of the best teams at set-pieces and you must be perfect in defence.
"The game looks like it does not end until they score. They had five extra minutes, but they could have given three or four more until they had scored.
"We often lose in the last minute, we need to improve that..."
