Real Madrid are in a precarious position following their 2-0 setback in the first-leg of the Champions League semi-final against Barcelona.
Iker Casillas refused to comment on the performance of referee Wolfgang Stark who sent off Pepe before Lionel Messi’s brace put the Catalan giants one step closer to Wembley.
“We can only keep quiet, bite our tongues and think about the second leg," Casillas said, according to AS.
"It is going to be very, very difficult, but when we get there we will try to recover from this position."
The Spanish shot stopper thought that his side had been in the tie until being reduced to ten-men, adding: “At first we were controlled, but, when you go a man down, when that man is doing very important work, it is clear that everything changes."
Barcelona will host Real Madrid at Camp Nou for second leg on Tuesday with both sides competing for a place in the final at Wembley Stadium.
