Real Madrid's Iker Casillas admits 'we can only bite our tongues and keep quiet' after Champions League semi-final first leg defeat

The Spanish goalkeeper opts to focus on how Madrid's recovery in second leg rather than the refereeing decision

Real Madrid goalkeeper Iker Casillas refused to be drawn on the performance of referee Wolfgang Stack after 10-man Madrid were left on the brink of elimination from this season's Champions League after losing the first leg of the semi-final 2-0 against Barcelona.

The dismissal of central defender Pepe gave Barcelona the advantage midway through the second half and a Lionel Messi’s brace put the Catalans one step closer to Wembley, but Casillas refused to criticise the referee and urged for concentration on turning things round in the second leg.

“We can only keep quiet, bit our tongues and think about the second leg," he told

“It is going to be very, very difficult, but when we get there we will try to recover from this position”.

And the Spanish goalkeeper admitted he felt his side were in a solid position before the red card, which he felt changed the game.

"At first we were controlled," he added.

“But, when you go a man down, when that man is doing very important work, it is clear that everything changes."
