Real Madrid CF goalkeeper Iker Casillas says they can't become "obsessed" with FC Barcelona."We must rely on this squad because it is young and has a lot of room to improve," said Casillas. "When the team matures, we will get the results everyone is expecting. Certainly, I know this team is exciting our fans. There's no reason to be obsessed about FC Barcelona. We know the team and what they've done, but we must find our way of playing. We're a new team and will try to quickly play our best possible football." (Photo: Getty Images)
