Xavi admitted disappointment after Barcelona's 0-0 draw at Rubin Kazan last night.

Barca needed a win to assure themselves of progress to the Champions League knockouts and instead face an anxious final two group games.

"We depend on us, the next two games are crucial and we will try to get the six points we are missing," said Xavi.

"They're very organized and do a great job defensively, so we have to congratulate them."

Barca teammate Zlatan Ibrahimovic missed a great first-half chance.

The Swede lamented: "We have had many more chances but no luck, we lacked a goal."
