Barca face Valencia tonight.
Roura said: "We do not think about these issues. We just talk about the game against Valencia.
"If we get the win against Valencia it will be an important step, but it will be a difficult game.
"It is one of the most complicated places to visit, a very difficult place to go. During the last years we have won a few times there. They have improved with Valverde and are a very dangerous team."
When pressed, he reiterated: "I will not say anything on the subject of Real Madrid. We're not going to get into media games. We talk about football and the game on Sunday. We do not talk about other things."
