Raul left Real last summer.
He stated: "Of course I cross my finger that in the end it will be Real Madrid, but as Barcelona remains in front it is difficult to see them losing the title. Barcelona's displays have been impressive.
"Real Madrid is still in my heart, when you have played for a club for 16 years, they do not leave you, just like that. But now I am with Schalke, my head is here and I give everything for this club."
