"I don't think we won because of the referee," he said.

"We played some extraordinary football in the first half. But we cannot allow ourselves to miss so many chances. I want to congratulate my players for what they did and also the Espanyol team because their display disrupted our initial plans," added Guardiola on the Barcelona club website.

Finally he had some harsh words for the Barca supporters who had provoked the incidents in the stands.

"The actions were both sad and disgraceful. We are the first to denounce it and it cannot be tolerated," he said.

Elsewhere on Saturday night, Real Madrid needed a last minute goal to beat Betis 2-1. Ruud Van Nistelrooy gave the points to the league champions, who had been reduced to 10 men following Marcelo's red card.

"We deserved to win," was all Madrid coach Bernd Schuster would say.

Finally Villarreal remain in contention at the top of the table after their 1-0 win away to Sporting Gijon. Villarreal will go to the top if Valencia fail to win on Sunday night, while Sporting have lost all five games this season.
