However, they could only muster a draw against Al Khaleej, who are fighting relegation from the Saudi Pro League.
Ronaldo could not get on the scoresheet and did not look very happy when a member of the opposing team's staff tried to get a selfie with him as he left the pitch.
As he tried to stand next to the five-time Ballon d'Or winner, he angrily shoved him aside as he headed towards the players' tunnel.

The Ronaldo fan shrugged and left the 38-year-old alone, whose side are now five points behind league leaders Al Ittihad.
Al Nassr had 22 shots but just six on target while they also had two-thirds of the possession and nearly double as many passes.
Ronaldo's side were stunned in the opening minutes when Fabio Martins scored in the fourth minute for the visitors.

Al Khaleej, who are three points off the relegation zone, were pegged back soon after when Alvaro Gonzalez netted the equaliser just before the 20-minute mark.
Ronaldo has scored 12 in 13 appearances since moving to Saudi Arabia after his contract at Manchester United was ripped up.
But his no-show on Monday night could cost Al Nassr the title with four games left in the season.

The Riyadh-based outfit were top when Ronaldo arrived but their standards have slipped, which cost Rudi Garcia his job as manager.
There have been reports that the Portuguese icon is not happy in Saudi Arabia and wants to return to Europe just months into signing.
He is reportedly desperate to return to Real Madrid, where he has forged much of his legacy, winning four of his five Champions League titles.
