Barcelona (0) v Benfica (0) Camp Nou, kick-off 7.45Barcelona are confident they can recover from a recent barren spell up front and see off Benfica in tonight's Champions League quarter-final at Camp Nou. Barca, who drew 0-0 in last week's first leg in Lisbon, have only found the net once in their last three outings.

Argentina forward Lionel Messi returned to training on Monday after a month out with a thigh strain, but is not yet ready to play, while Eto'o is receiving treatment to a bruised leg, although he will start.

Frank Rijkaard's attention is also likely to be focused on his injury-hit defence. Mexican centre back Rafael Marquez, versatile Brazilian international Edmilson and left back Silvinho are all out injured, while midfielder Thiago Motta, who can also play at the back, suffered a minor thigh strain against Real Madrid on Saturday. Captain Carles Puyol received a blow on the head against Real, but was back in training on Monday and is likely to be partnered by Oleguer in central defence.

Ronald Koeman also has major injury worries after striker Nuno Gomes damaged his left knee in Saturday's 2-1 win over Belenenses. Gomes will miss the match and is likely to be sidelined for three weeks. Brazilian defenders Alcides and Nelson are also injured.

Koeman is expected to defend in depth and, like last week, rely on counter-attacks from Italian winger Fabrizio Miccoli and former Barcelona midfielder Geovanni.
