Esteban Granero insists he can do even better for Real Madrid.
Real fans are convinced the midfielder produced his best performance for the club in Saturday's victory over Espanyol.
But Granero says: "I feel good physically, I'm playing more and now I'm more confident, but I always say that my best is yet to come."
"Besides, I don't like to talk about what my potential is because every time I've done so in the end I've surpassed it. I feel lucky."
He added: "Barca continues to be ahead of us by five points, but of course it is not definitive. We know we must not fail, we are on the right track. Of course we can catch them."
