A brace from Fernando Torres and a goal each from Ryan Babel and Alberto Aquilani secured the win for Liverpool.
“It was a good game. We were trying to play well for the fans and score goals,” said Benitez.
“It was an important goal in an important week.”
Aquilani scored his first goal for the club.
“It was really good for Aquilani and really good for the team,” he said.
“He has shown he has quality and he will have more confidence and that is good.
“We have seen a lot of players playing well today and that is good for me because it gives me more (selection) problems.”
