Benitez said: "I told Carra before the game he must score three goals this season. He has started early!
"I thought it was a good result for us. When they scored I was a bit worried but I always have a lot of confidence in my team.
"We scored three goals and could have added a couple more at the end when we missed some clear chances. In the end 3-1 will do and we will continue to get better as we play more games."
