Benitez was delighted by Chelsea's display.
"I think it is important to see the team working hard and defending well," he said. "We have another clean sheet after Villa, where we were playing really offensive football.
"We could manage and we could control against a good team. They were well organised and pushed and were quite dangerous on the counter-attack, but we were doing our job in defence and that is something we have improved and can keep on improving.
"This kind of game - 1-0 - a free-kick, corner or counter-attack can make a difference so until the end they were pushing so we did well."
