Ronaldo scored his 100th official goal with Real Madrid against the French club.
He remarked: "I didn't expect to score my 100th goal so soon. I'd like to thank my teammates and the manager, who gives me the chance to play and grow as a player and as a person.
"It was important to win and qualify for the next round. We made it. We're calmer now that we've won our first four games.
"We all played very well against a team that made things difficult for us. We must keep this up and avoid comparing ourselves with other sides. We're more mature than last year and we're having a good run, but we must also take things slowly."
