Last season, it was the Frenchman who was blamed for United's win at the Etihad.
"It was a big statement," said the Frenchman. "We have sent a message to our rivals that this year we can be a force. To win like that is always special.
"It's a different feeling from last year, and a different feeling for me as well.
"Last year I was involved in the third goal in a bad way, so this was a little revenge. I just want to share this moment with our fans.
"Last year was a little bit sad because we were losing 2-0 and came back, but in the last minute Robin scored that free-kick. This year it was not the same scenario, and we are very happy.
"I like these big games. Every big player should be great in these games. We showed what good players we have in our team because we put in a very good performance."
