Real Madrid skipper Casillas: Atletico Madrid will be tough test

Real Madrid skipper Iker Casillas says they can't take this weekend's derby with Atletico Madrid lightly.

Atletico's last win in the fixture was more than 12 years ago in October 1999, when they won 3-1 at the Santiago Bernabeu.

However, Real goalkeeper Casillas is taking nothing for granted, telling Marca: "We are not the favourites, nor are we stupid."

"The derby is more than a match for Atletico. We have gone a long time without losing and they will want to finally break that streak."
