Barcelona shot-stopper Victor Valdes has stated that the referee could play a key role in the upcoming Champions League semi-final against rivals Real Madrid.
The first leg of the tie will be played at Santiago Bernabeu on Wednesday evening, and Valdes commented to the club's official website: "We are a team with players who are winners and we want to repeat the triumphs with Barcelona. So, we just have to keep going, and go all out against Real Madrid.
"We know what can happen against Real Madrid. We must take what comes, and it may depend a lot on the referee whether we can play our game or not. But we’re not obsessed about these things."
Valdes then went on to say that Barcelona should just try and play their own game if they are to be successful.
"We have to do our thing and play the game that suits us. The key will be ball possession, and we have to pass, and pass, until we get a chance on goal."
The Catalan giants edged closer to retaining their La Liga crown courtesy of victory over Osasuna on Saturday evening.
