Carragher was part of the Liverpool teams that held Barcelona to 0-0 draws at the Nou Camp in 2001 and 2002. Tonight he hopes to get the hat-trick.
"We've had some good results in the past and I'm sure 0-0 would be considered a good score this time as well. We're playing against the European champions and against a side who went close to becoming world champions as well, so we know it's going to be difficult," said the Liverpool vice captain.
"We've had ten days since our last match and we went to Portugal to prepare for this game, so we are ready. The important thing on the night is to play well and stay focused because Barcelona have top quality players.
"It's going to be a great occasion for everybody involved and we are all looking forward to it."
