Barcelona midfielder Sergio Busquets admits Real Madrid's poor start to the season has surprised him.
Barca have opened up an eight point lead on Real.
Busquets said: "We're looking to ourselves. There's a long way to go in the league. We go out to win every match and that's all.
"The gap is surprising, but this has only just begun. Now we're focussed on having a good match in the Champions League."
