Cristiano Ronaldo showed all of his class during Al-Nassr's AFC Champions League game against Persepolis on Monday. 

He is second to the ball and tumbles over, with the referee quickly pointing to the penalty spot to the incredulity of Persepolis' players. 

Replays showed that there had been no contact on Ronaldo and credit to the Portuguese superstar he was quickly on his feet and wagging his finger to tell the referee to correct his decision. 

Al-Nassr, who went down to 10 men when Ali Lajami was sent off in the 17th minute, eventually drew the game 0-0 and so it makes Ronaldo's honesty even more honourable.
