Real Madrid fullback Marcelo admits he doesn't trust Barcelona.
Barca can deliver the title to Real if they defeat Atletico Madrid in the final weeks of the season.
Asked if he trusted Barcelona, Marcelo was quite clear: "No, I only trust Real Madrid. We have to do our work and then see what happens. We're not going to trust anyone. First we have to win our matches. We're not going to think about other teams; we have to think about ourselves, win and then we'll see."
