At Madrid v Barcelona preview

Atletico Madrid playmaker Arda Turan has been ruled out of Wednesday's Champions League quarter-final second-leg at home to Barcelona, although forward Diego Costa has been included in the squad.

Arda has failed to shake off a groin problem, while coach Diego Simeone remains hopeful Costa will have recovered sufficiently from a thigh muscle strain to play a part in the match at the Calderon.

The two Primera Division sides square off at the Vincente Calderon stadium in the return leg with Atletico holding a slight advantage after last week's 1-1 draw at the Nou Camp.

Barcelona captain Xavi believes his side "must steal the limelight" against Atletico Madrid on Wednesday if they are to reach the semi-finals for the seventh-straight season.

"This is a final," Xavi said. "It's going to be complicated because we struggle to create goalscoring opportunities against Atletico.

"In all of the games we have played against them this season, we have been unable to take the lead.

"We must steal the limelight, dominate possession and attack them. The fact that we have to win this game will be an advantage for us."

Barca must score as a goalless draw would see Atletico go through thanks to Diego Ribas' away goal.

Barcelona coach Gerardo Martino believes his side must score first.

"Both teams know each other very well," he said. "I think both have played at a very high level in different styles, but what hasn't happened is that Barcelona have gone in front," he said at his pre-match press conference on Tuesday.

"That is very important and even more so in this case. We will try to score first and that will allow us to manage the game in a different way."

Barca go into the encounter in the Spanish capital after a 3-0 win over Real Betis on Saturday - their fifth straight win in the league - and Atletico are not taking Barca lightly,

Midfielder Tiago Mendes said: "The tie is wide open. We are not going into the game thinking that a goalless draw is enough. We are going to play as we always do, trying to score goals.

"This is a great opportunity for us because we are playing against a great Barcelona side and in the semi-finals of the competition.

"We are very excited because we can make history."

Atletico have not reached the final four among Europe's elite since 1974.

Barca coach Gerardo Martino will be without injured defenders Gerard Pique and Carles Puyol.

Marc Bartra will partner Javier Mascherano at the heart of the defence.
