Eidur Gudjohnsen gave Barcelona a 1-0 win at Anfield, but Rafael Benitez's men progress on the away goals rule courtesy of a 2-1 win at the Nou Camp 13 days ago.

After dumping out the holders, Carragher told ITV1: "The club's got a great history in Europe but besides winning finals this is probably the biggest result in Europe we've ever had.

"Barcelona are the best club side in the world, even though we've knocked em out.

"We were hanging on - with 10-12 minutes to go we were just praying for the whistle.

"We didn't realise until a few seconds after the blew it he had - we got there in the end."

Captain Steve Gerrard added on ITV1: "We were unlucky not to go in at half-time ahead.

"Barcelona are so good going forward, they play such nice football, but we stuck in there and are in the last eight now.

"We've got great spirit, grit and determination - people were throwing bodies about and that's one of the reasons we're through.

"It gives us great confidence, going through against the best side in Europe over two legs."

Benitez insisted his side were worthy winners of the tie.

"It was a strange game. We started really well, we put them under pressure," he told ITV1.

"When they started moving the ball, you need to be compact and organised.

"Playing against a good team, always it's important to win. The atmosphere was fantastic. It was almost perfect."

Benitez agreed with Carragher that Liverpool could take great heart from eliminating the holders, but added: "We have confidence now and I think it will be the same for the rest of the teams."
