The Real captain said: "We have many chances to win at the Camp Nou. For them the game will be much more important if they lose against the Valencia. For us now the important thing is to win against Osasuna.
"We have the opportunity to go to Barcelona and to try to continue and increase our lead."
Barcelona star Leo Messi, who took part in a promotion with Raul, said: "We have the luck of being at home in the first game and that must be in our favor. I believe that in these duels the fans have a big influence.
"If I score, I will dedicate it to my family, which is with me always in the good and the bad times."
Raul added: "Messi is a unique player because he is so young. The personality that he has to play and to handle in the last years all this pressure is incredible. To be a such a media star is not easy and his humility and hard work is helping him. He seems a good person."
