Casillas urges Real Madrid to take frustration out on Liga title

Real Madrid captain Iker Casillas says they must finish the season strongly after this week's Champions League heartbreak.

Casillas has urged Jose Mourinho's star-studded squad to bounce back and turn their seven-point lead over Barcelona into silverware.

"It has been a harsh blow and it's hard to get back on our feet, but we must carry on and focus on what remains of the season," said the Spain international.

"Penalty shoot-outs are like the lottery and we lost due to bad luck. That's all there is to it."
