Barcelona coach Frank Rijkaard could not resist a sly dig at his Liverpool counterpart Rafael Benitez ahead of tonight's Champions League match at Anfield.

The European champions are aiming to overturn a 2-1 deficit and remain on course to retain the trophy.

Liverpool boss Benitez believes they will have to withstand a three-pronged attack featuring Ronaldinho, Lionel Messi and Samuel Eto'o.

Rijkaard, who refused to give any clues to the system he will employ, responded: "It is great to play against a team whose manager already knows everything.

"Maybe it is his way of hiding any kind of anxiety he might have himself. The people who know everything and say they know everything are the ones who know the least amount."

Rijkaard insists his players will be lifted and not intimidated by the special Anfield atmosphere.

He is quietly confident of claiming a place in the quarter-finals even though they go into the second leg match on the back of a league defeat by Sevilla at the weekend.

"Liverpool have a great crowd and we will be motivated by them," said the Dutch boss.

"It is a great opportunity for us to put things right from the first leg. We are playing away from our stadium and have nothing to lose.

"We will just go for it and see what happens. Some people may think Liverpool are already through and that takes the pressure off us.

"Maybe they will find it hard in front of their own fans. We have an excellent group of players and a team strong enough to spring a surprise."
