Riise could start against Chelsea

Liverpool manager Rafael Benitez has no new injury problems ahead of tomorrow's Champions League semi-final second leg at Chelsea but has yet to decide on his defensive line-up.

With Fabio Aurelio out with a groin problem Benitez could install John Arne Riise - who scored the critical own-goal as a substitute in the first leg 1-1 draw - at left-back.

Benitez could also recall Sami Hyypia to centre-back, move Jamie Carragher to the right and switch Alvaro Arbeloa to the left while there could also be a place for Steve Finnan in either full-back spot.

Benitez must also decide whether to include in-form Peter Crouch up front in preference to Ryan Babel on the wing. His inclusion of Crouch in the last round against Arsenal upset the Londoners' gameplan and paid dividends when Babel replaced the England striker to score his team's fourth.

Benitez was confident ahead of that tie and his mood is no different this time round.

"We will score. We will win and we will get to the final," he said today. "The team is ready and focused, they are concentrating on the job and confident.

"I am not really worried about how people judge our season, I am only concerned about how we progress, and how we will feel after the game when we are happy with ourselves.

"We have guaranteed fourth position now, that has been our aim. Now we intend to go to the Champions League final.

"Our aim is always to win trophies, that's simple, and we intend to do so this season."

Frank Lampard, who played in the 1-1 draw at Anfield but missed out on their league win over Manchester United last Saturday because of the death of his mother, looks set to return for Chelsea.

Goalkeeper Carlo Cudicini remains out of action with a damaged hamstring.
