Benayoun, who scored the winner at the Bernabeu on Wednesday in the first leg, is happy to have Gerrard back for the return leg at Anfield on March 10.
"I was delighted to have scored, but the most important thing for us was the win. It was the perfect result, a clean sheet and an away goal," he said.
"It was hard against Real, they have great players and it is a difficult place to win. But we achieved our objectives.
"Now we have great confidence for the second leg at Anfield, we will have the fans behind us and Steven Gerrard will be fit by then. We all believe now that we can reach the quarter-finals.
"It is easier when Steven is playing, so we had to work extra hard to cover for his absence, which is not an easy thing to do.
"He is the most important player in our squad. But we did do the job well.
"We were facing a Madrid side who had been in outstanding form, this has been a key time for them in their season.
"So that makes the victory even better. We believe we can finish the job, and we will have Steven back for the second leg."
