"Luis is very disappointed. I said to him after the game that he had made a big mistake. You can't lose your control before important games. Maybe for the future this will be good for Luis and the rest of the players because they can see what could happen," said Benitez.
"It is a big blow for us as he is a player who scores goals on important occasions. He can change a game and so of course we are going to miss him in Cardiff."
