Real Sociedad manager Imanol Alguacil has been full of praise for Hansi Flick's Barcelona ahead of tomorrow's La Liga clash with the Catalans.

Barca head into the game on a superb run of form and face a Real Sociedad team that have only managed one home win all season.

Alguacil says he's been enjoying watching Barcelona this season and thinks they are the "sensation of Europe."

"It's really amazing, it speaks very well of this team and this coach. The truth is that it's a joy to watch Barcelona play," he told reporters.

"On an offensive level they have changed their style, I think they are much more direct, they do more damage to the opponent, they don't speculate, that's why they create so many chances and so many goals.

"They are capable of hurting you, not only through passing, but also through transitions. We all praise the high and good line, the high pressure... There are many good and different things, for some reason they are the sensation of Europe.

"We all like to play this type of match, it is a very good opportunity to prove ourselves and, what's more, in front of our fans.

Barcelona boast a good record away to the Basque side in recent years. They are unbeaten in their last eight away games against Real Sociedad in La Liga.
