Barcelona coach Xavi says they're obligated to win the Europa League.

Barca will face Manchester United for a place in the final 16.

Xavi said, "But we are also always up against teams who will also be obliged to win.

"In the press, you like to talk about obligations, failures... It's a challenge.

"We are going to try to win it. The club has never won the Europa League and we're going to go all out to try and win it, there is nothing else for it."
