Barcelona legend Johan Cruyff says they proved little in their victory at Real Madrid on Saturday night.

While Barca regained the lead, Real still have a game in hand and Cruyff wasn't overly impressed by the visitors' performance.

"All it proved was that Madrid are serious contenders to Barca's title," said Cruyff.

"The game at the Nou Camp won't be decisive. The title will be decided by the team which suffers the least failures during the season.

"At 1-3, Barcelona lacked ambition. They could have achieved a crushing result and made Real Madrid crumble."
