Barcelona midfielder Andres Iniesta insists they won't underestimate Real Madrid.
Iniesta was asked if this season's Real Madrid team were 'weak'.
"That would be a foolhardy thing to say. When I get asked about Real Madrid I always say the same thing: they're a powerful rival, even more so at home in front of their fans.
"It's too early for this game to be definitive, we can't kid ourselves, but we want to stretch that distance at the top of the table. We have to play our way and if we do we have a chance of going home with all three points."
