Barcelona head coach Xavi says his players are determined to put right their 1-0 defeat to Shakhtar Donetsk in the Champions League.

A win would have been enough to guarantee the reigning LaLiga champions' place in the last 16 but their progression is now far from assured.

And the 43-year-old declared that his team were "angry" at the manner of their defeat.

He said: "Nothing has gone as planned.

"We wanted to guarantee qualification but it's a very clear step backwards.

"The Champions League demands the highest level but we haven't found it. We're angry.

"We couldn't fail and we have failed. It's a big mistake on our part."

The 2015 European champions have now won just three of their last six matches — a run that also includes an El Clasico defeat to Real Madrid.

But their boss insists that they are suffering from a lack of confidence rather than anything more permanent.

He said: "Not long ago we played very good football.

"We are at a low level of confidence and we have to reset. We didn't feel comfortable in the game. 

"It's a bad feeling we have in the dressing room and also me as a coach.

"We are doing things wrong in general, both in attack and defence. We are conceding too much.

"It's my job as a coach and the players to take a step forward. It's up to me to regain dynamism and confidence. 

"The players have a high level and they can do much better than what they are doing."
