Barcelona coach Tito Vilanova has taken a swipe at Real Madrid's mega spending.
The two teams clash tonight at the Nou Camp.
Vilanova said: "The more games you play, the more you know. We know what they'll do, how they'll approach the match and they know what we're going to do. I don't think there will be any surprises at this point.
"They have a fantastic team that cost a lot more millions than Barça's and it's possible that they'll win."
