"Fabio Aurelio, also, has returned well from injury. All of that is positive for the rest of the season."
The victory ended a five-match winless streak and Benitez now hopes to gather momentum.
"Winning is the target, so now we have new targets," he said. "We are in a very bad position because now we cannot win the Champions League again, we know that, so the next game has to be won.
"The players know we have had a bad run of games. We could have done better, but we won this match and we have shown we can win in difficult circumstances.
"I am trying to be very positive. The players know that when we have Gerrard on the pitch and when we have our other big players available, we will improve."
