Barcelona coach Tata Martino says they won't hold back against Champions League opponents Atletico Madrid.

Tuesday's match will mark the fourth time the two teams have met this season, with each game so far ending in a draw.

"The secret of the game will be to match Atletico in intensity so that they don't overcome us, and our biggest strength will be to play like Barca always do," Martino said.

Asked whether Barca would be brave against Atletico, Martino said: "If this team wasn't brave these boys wouldn't have been able to achieve everything they have done in the last few years, and this club wouldn't be where it is now. That requires bravery, and it's guaranteed, because very few teams play the same way we do.

"I can't imagine we'll spend the game running behind the ball, we can't forget that we are Barcelona."
