The attacking midfielder has insisted that the Hoops did not deserve a draw at Camp Nou, and added that the Blaugrana are well on their way to the knockout stages
The Scottish champions appeared to be on their way to a hard-fought 1-1 draw, but Jordi Alba's goal well into stoppage time eventually helped Barcelona to the full three points, much to the satisfaction of his team-mate.
"It would have been unjust if we hadn't won. After their goal, they closed themselves off at the back and it was very difficult [to break through]," he was quoted as saying on the club's official website.
"We were convinced that the ball would eventually go in. It could have happened earlier, but the game isn't over until the final whistle.
"It’s never easy to maintain your concentration on defence when the team is on the attack all game long. Marc [Bartra] and [Javier] Mascherano were fantastic.
"The objective was to win nine points, our position in the group couldn't be better ."
Barcelona continue their Liga campaign on Saturda, when they travel to face Rayo Vallecano.
