Ronaldo scored in their 2-0 win over Al Ahli, moving Al Nassr eight points clear at the top of the Saudi Pro League table.
In his post-match interview, Ronaldo found himself taunted by Al Ahli fans, with the club having won a second consecutive Asian Champions League title earlier this month.
As the taunts began during the interview, Ronaldo was quick to remind the supporters of his European Champions League titles.
The Portuguese shouted: “Five Champions I have.”
Ronaldo beamed as he held five fingers up to the crowd, adding: “I have five!”
During his European career, the now 41 year-old striker won the Champions League four times with Real Madrid and once with Manchester United.
