Inter Milan won the game 1-0, following a goal by former Barcelona striker Samuel Eto’o.
“It was important to win today,” Benitez declared to SkySport.
“I think the side showed some good stuff out there and I was very happy with the contribution of [Samuel] Eto’o.
“He is in a great moment of form, but I don’t think we are dependant on him.
“We controlled the game after the goal but credit must be given to Cagliari for the chances they created.”
