"The game was another example of the influence Gerrard has on our team, he is so special," said Benitez.
"To score twice like that, and with a really good first goal, when you have only just recovered from an operation shows just how important he is to us.
"But it was not just Steven. It was a very sound team performance, everyone worked so hard, and that is what pleased me most.
"But he showed that he can change games on his own. He can improve, and he knows it, following the operation.
"But his impact was the most positive thing from the game. His first goal was amazing, a fantastic effort and it altered the course of the match.
"You may not see many such goals in 10 years it was that good."
