The Portugal international claimed that he is not solely motivated by goals and insisted that he was enthused by his rival's heroics against Bayer Leverkusen last week.
While the two players are often portrayed as rivals, the Portugal international insisted that he took just as much satisfaction out of Messi's stunning feat in the 7-1 rout of the Bundesliga outfit as everyone else.
"I’m happy for Messi. I’m happy for football," Ronaldo told reporters in Madrid ahead of his side's last 16 second-leg clash with CSKA Moscow on Wednesday night.
When asked if he thought he might equal Messi's achievement, the former Manchester United player humbly replied, "I’m not sure if I’m capable of one day scoring five goals [in one game]. I hope I can."
Ronaldo went on to say that he is not concerned by people's perception of him, and insisted that he is not solely motivated by the glory which comes with breaking goalscoring records.
"I don’t know if I’m more respected here now, but that’s not what matters to me," the 27-year-old explained. "I’m still the same person, with all my defects and virtues.
"I only worry about myself and my team. Goals don’t mean anything to me. To score or not doesn’t mean anything to me."
Ronaldo has racked up 126 goals in 127 appearances for Madrid since joining from Manchester United in 2009.
