Barcelona coach Pep Guardiola has backed his side's style to overcome Chelsea's power in the first leg of their Champions League semi-final clash.
The two sides will lock horns at the Camp Nou on Tuesday evening in the first leg of an intriguing last four encounter.
Barca have set their domestic league alight this season with several attacking master-classes which have ripped opposing defences to shreds and Guardiola believes the philosophy of the Catalan club will win the day against Chelsea.
"Barca is obliged to play an attractive game and there is no other way I know for us to play," said the former club captain.
"Tuesday is a big chance for us to show the world our style and we will be trying to seduce with our way of playing.
"Our principles are not for renouncing and we will never give them up as long as I am coach.
"I am very impressed with Chelsea, they are a powerful team and a lot stronger than us, so we must keep hold of the ball and make the difference at home.
"Our intention is to play our usual style which means attacking while at the same time making sure that we do not concede a goal.
"I saw in Chelsea's game against Liverpool the danger they pose in the air especially from (Didier) Drogba and so we have to be careful to concede as few free-kicks and corners as possible.
"Chelsea have more to their game though than just power and if you let them play then they can create a lot of danger with footballers who can run 20 or 30 yards with a ball and we just have to be aware of that.
"We have played other teams though that have a similar approach to Chelsea so we do know what to expect."
