Cristiano Ronaldo appeared to throw water on a cameraman and told him to go away after Al Nassr's draw against Al Shabab.
Ronaldo fired blank as Al Nassr drew 0-0 with Al Shabab in the Arab Club Champions Cup on Friday.
He entered the fray as a second-half substitute but failed to influence the game.

And he cut a frustrated figure following the final whistle as he remonstrated from the sideline before taking his anger out on a cameraman.
Whilst having a drink, the 38-year-old seemed to throw water on a cameraman then gestured him to move away in a furious outburst.
Ronaldo echoed a similar thought on social media as he made his feelings known.

On Twitter, he wrote: "Tough 1st game in the group stage! 2 more games to go. We keep fighting!"
Al Nassr have two more Arab Club Champions Cup matches as they look to book their spot in the next round of the competition.
They take on Monastir next Monday then meet Zamalek next Thursday.
This was Ronaldo's first appearance for Al Nassr since former Manchester United forward Odion Ighalo accused him of 'playing for money, not passion'.
Ighalo, who was at Al Hilal last season, explained: "When you are young, yes, you play for passion. Back then, you don't care about money. But at my age, I am in the final stretch of my career, I don't know if it will be one, two years or when God will tell it to stop.

"I know it won't be more than three years. I've played for passion all my life, now it's for money. I'm not one of those players who come and say: 'I play for passion'. Brother, it's money. At the end of the day, it's money."
He added: "Is Ronaldo still playing out of passion? Ronaldo has earned 100 times more than I have in my entire life and yet he went to Saudi Arabia.
"Did he do that out of passion? It's for money, bro."
