The Portuguese has now scored 16 goals from 13 games in La Liga, and his coach was at a loss for words to honour his achievements.
"Cristiano's talent puts him in a different category altogether, it's out of this world," Football Espana quotes the Italian as saying.
"He scores so regularly and with such incredible ease. It's hard to find new words to describe him."
Ronaldo is also top scorer in the Champions League with eight goals in four games.
