The 21-year-old has nothing but praise for his Madrid team-mate and believes he deserves to be rewarded for his impressive performances
The Portugal international is one of the main candidates to win the prestigious individual trophy alongside Franck Ribery and Lionel Messi.
Casemiro has stressed that it would only be logical if Cristiano Ronaldo emerged victorious following his fine performances in 2013.
"He has to win the Ballon d’Or. He is spectacular," Casemiro told the official Madrid website.
"There is no doubt that he is the best player around right now. If he scores two goals in a match, he always wants more and keeps on giving.
"I always watch what he does. He trains well, is always happy and has always helped me."
The Brazilian midfielder then went on to voice his admiration for former Madrid greats such as Zinedine Zidane and Ronaldo.
"Zidane is the best player and a great person. Ronaldo Nazario is spectacular. It's a dream to be at the same club as these great players, I never imagined it."
Casemiro has made three Liga appearances so far this term.
