WATCH: Cristiano Ronaldo tells referee NOT to give him a penalty after going down in box in Al-Nassr's AFC Champions League clash against Persepolis

Ronaldo was brought down in the Persepolis box in the early stages of the AFC Champions League clash in Riyadh. Chinese referee Ma Ning quickly pointed to the spot but the Portuguese star joined the Persepolis players in protesting against the decision, wagging his finger at the official and telling him it was not a penalty. Ning then went to review the incident and decided to reverse his initial decision.

Ronaldo and his Al-Nassr team went on to draw 0-0 with Persepolis, with the 38-year-old missing the home side's best chance - lashing narrowly wide of the target in the second half. The point saw his side progress to the round-of-16 of the AFC Champions League, with Persepolis sitting five points behind them.

Al-Nassr have one more AFC Champions League group game to come - against Istiqlol Dushanbe on December 5. Before that, however, they will take on Al-Hilal in a top of the Saudi Pro League clash on Friday. Al-Hilal are four points ahead of Ronaldo's team heading into the tie.
