Real Madrid captain Iker Casillas feels their Champions League quarterfinal is wide open after drawing 0-0 at Atletico Madrid in last night's first-leg.

Real will play out the return-leg at the Bernabeu next week.

Casillas said: "The first half bore no relation to the second. Real Madrid deserved much more from the first half, but we were up against a fantastic Oblak. After the break Atlético calmed things down, prevented us from attacking on goal and controlled that aspect of play.

"The tie is wide open. A 0-0 result ensures for a great second leg and I think both teams still have a chance of going through. We're hoping the fact that we're at home will mean we put in a good performance, feed off the fans' energy and get through the tie, which we knew from the beginning wouldn't be easy."
