Dan Agger has no doubts Liverpool can handle Europa League opponents Benfica.
Benitez's former club Valencia or Fernando Torres' previous employers Atletico Madrid await the winners in the semi-finals but defender Agger said they were not worried by any side.
"This is the last trophy we can win so we have to give everything we can to win it," said the Denmark international.
"We have to show it on the pitch and I think we did against Lille. If you have to win a tournament like this one you should beat them all."
