Barcelona winger Pedro has admitted that the Catalan outfit cannot afford to lose Sunday's Clasico against Real Madrid at the Bernabeu.

The La Liga holders currently sit third in the table on 66 points, but defeat to the capital outfit at the weekend would leave Madrid with a seven-point lead over Gerardo Martino's side.

"A defeat would make it tough to pull ourselves back into the title race," he told Barca TV.

"But we are coming into the game in a good run of form and we know it's all to play for there. We all want to put in a great performance and keep our treble hopes alive.

"Madrid might just be favourites because they are playing at home, but we know in this type of game there are never clear favourites at all - anything can happen."

Pedro has scored 14 league goals for Barcelona this season.
