The French club hold a 1-0 lead from the first leg and present a completely different challenge to that of the Barclays Premier League's bottom club.

It is unlikely, therefore, Benitez's team selection will be as attacking as it was against Pompey, although one consideration may be the fitness of man of the match Alberto Aquilani who missed training today through sickness.

Liverpool need to score tomorrow but, crucially, although just one will get them back into the tie they have to make sure they do not concede a potentially-damaging away goal.

"On Monday we could see the football the side can play and hopefully we can see that against Lille, although it will be difficult," said Benitez.

"Everyone wants to see attacking football and we try to approach every game in the same way and sometimes you can but sometimes you cannot.

"We knew we needed to push Portsmouth from the beginning because they are not having an easy time but that was a different game.

"We played good football and the fans were happy and it was good for confidence - but we must win [against Lille] because we lost the first leg.

"We have to make sure we do the right things: score, keep a clean sheet and do good football things."

Benitez has urged his players to rise to the occasion in front of an expectant crowd at Anfield.

"The fans know this is the last opportunity to win a trophy so hopefully there will be a good atmosphere," added the Spaniard.

"And the players know it is the last opportunity to win silverware so everyone will try their best tomorrow.

"I think it is very important for everyone and I'm sure the players know.

"It will be positive to keep winning games for the confidence of the players.

"Winning and scoring goals, that is the way to bring confidence back.

"They have quality and confidence now and we play at Anfield and we know what that means for the majority of teams."

Benitez is hopeful a comeback in tomorrow night's tie will provide a boost to their Premier League campaign.

"It is important for us to finish in the top four and also win trophies," he added.

"If you can manage to do both things at the same time that is fantastic."
