"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."
