The striker scored Real's opener in the triumph.
Benzema stated: "It was a great night and all of us put in a great performance. I'm really proud and happy with my display today. I now feel very good and after scoring the first goal, I felt that the fans were with me, that's really important for your confidence.
"Since a young age, I've lived with criticism. I work hard and sometimes you score a lot of goals and on other occasions you don't. I'm not a striker who always wants to score, I like to do my bit for the team and that's why I work so hard in training. I enjoyed myself today, I got my goal and it was a game with a lot of action."
He added: "We know that we're here at Madrid, the best club in the world and the fans always support me. At times, it's to be expected that I come in for criticism, but I'm always here trying to help the team. We're all very happy because we put in a good performance and we're now looking to continue on in this vein in LaLiga."
