Barcelona coach Xavi admits there's a frustration they're now out of the Champions League.

Barca were bundled out of the competition at the group phase and now face a Europa League playoff against Manchester United.

Xavi said: "We lacked a certain maturity. In Munich we had a good first half, but at the right moment we failed.

"We were also good at home against Inter, the people enjoyed themselves, but we lacked maturity. And in Milan, I don't make decisions, the referees, we should have had the maturity to at least draw that game.

"It makes me angry not to hear the Champions League anthem. But the Europa League is a European title and if we reach the semifinals people will be excited.

"Liga-Europa League double? Of course I sign.

"You have to aspire to all the titles. The club has made a great effort and you have to prove it. The pressure is above all on me and I accept it."
