VIDEO: Cristiano Ronaldo left in stitches as fan asks Al-Nassr superstar to do 'SIUUU' celebration outside stadium

Five-time Ballon d'Or winner Ronaldo has become very well known over the course of his illustrious career as the Portugal international has become the sport's top goal scorer in history. However, the other thing he has become well known for is his iconic 'siuuu' celebration and when a fan asked Ronaldo to do the celebration alongside himself, the Portuguese forward was left in stitches.

Ronaldo has become very loved since his move to Saudi Arabian side Al-Nassr. However, the 39-year-old has not been able to win any trophies for the club as Al-Nassr have struggled to find the kind of form they had hoped for when they signed Ronaldo.

The Portugal international is set to return to action when Al-Nassr take on Al-Taawoun on Friday, January 17 as they look to close the gap on the top of the Saudi Pro League standings.
