WATCH: Portugal's cyclists hit the Siu! Olympic athletes pay tribute to Cristiano Ronaldo after winning gold medal in France

Portuguese cyclists Luri Leitao and Rui Oliviera helped Portugal win their first-ever Olympics gold medal in track cycling. After achieving the historic feat in Paris and receiving their gold medals, the duo performed their country's sporting icon Cristiano Ronaldo's famous 'Siu' celebration.

The iconic celebration has become a trademark for the 39-year Al-Nassr star that sees him perform a mid-air pirouette before exclaiming "si!" (sometimes spelt "siu") - which is Spanish for "yes!" - upon landing. It is an expression of delight at scoring. After Ronaldo jumps and lands, supporters normally join the player in roaring the word, producing a booming sound reverberating throughout the stadium.

The former Manchester United and Real Madrid star will be back in action on Wednesday as Al-Nassr begin the new season with a Saudi Super Cup semi-final clash against Al-Taawoun.
