Ronaldo's long-standing rivalry with Lionel Messi has often been subject to heated debate with football's biggest prize, the Ballon d'Or, shared amongst them over the past decade.
However, Bayern Munich right-back Joshua Kimmich feels Ronaldo's goal ratio, especially in UEFA Champions League football, proves he is the more complete player, over FC Barcelona's Messi.
"When it comes to goal quotas, Ronaldo is in the lead," Kimmich told Bild. "Especially with regards to the goals in the Champions League.
"Messi is a completely different type of player. Ronaldo is perhaps more complete in terms of skills themselves.
"Messi is more a dribbler, Ronaldo the final player. I cannot say this one or that one. I am glad that I am allowed to witness both.
"Such a player as Ronaldo, you can only turn off as a whole team anyway. He is a goal machine, which has an insane goal quota. We have to make sure that he cannot continue his run."
Ronaldo is the leading scorer in Europe's elite club compeititon this season with 15 goals in 10 games.
