Barcelona midfielder Seydou Keita is refusing to write off the threat of crisis club Real Madrid.

Keita said: "For me, football is always about ups and downs, and now it's down for Madrid. For us, everything is good, but the season is very long.

"(Bernd) Schuster and Madrid are in a moment a little bit difficult, but we have to be careful, because there is always going to be time for an upside."
