Ronaldo has scored in 11 straight league fixtures for the Italian champions.
The 35-year-old Portuguese now has 24 goals this campaign.
On his part, Messi has gone four matches without a goal.
The Argentine superstar has, however, netted 14 times in 19 LaLiga games so far.
“It’s normal that he continues to score, he is a predatory striker, he loves to score, any day he plays he will score,” Messi told Mundo Deportivo when asked about Ronaldo’s recent performances.
“He has many good attributes as a forward and at the minimum, he converts.”
