The former Netherlands star has spoken of his admiration for the Portugal international, and believes people envy the attacker because of his looks
The Portugal international often gets a hostile reception at away games, while has has also been targeted by a number of opponents throughout his career.
Gullit, however, has nothing but praise for the 27-year-old and compared his situation to another former Manchester United star.
"I think Cristiano Ronaldo is a phenomenon. The same thing happens to him as it did to [David] Beckham; people criticise them because they are envious that they’re very good-looking," Gullit said to ESPN.
"For me, he's the ideal player. He's fast, tall, is good with his head, is technically good, shoots penalties, takes good free kicks and he’s a leader.
"I think that Real Madrid love having Cristiano Ronaldo as a player."
Ronaldo has netted 18 goals in 14 appearances for Real Madrid so far this term.
