The Portuguese ace revealed how this gesture has helped him connect with fans around the world, even if they did not know what it meant...until now.

One of Cristiano Ronaldo's signature moves has to do with what he does once he has found the back of the net, and fans can't seem to get enough of it.

The footballer's goalscoring celebration has been the subject of many theories as years have gone by, but today, in an interview with the website Soccer.com, the footballer shared the truth behind this iconic move, which made its way into a Ballon D'Or ceremony years ago.

The striker recalled the moment in which he began celebrating his goals with this move, six years ago.

"We were playing a game against Chelsea in the United States, and it just came to my mind. I just scored and I yelled 'si' (yes). It was truly a natural thing. I started doing that from that day on, and fans seem to like it," Cristiano told the aforementioned website.

The footballer, during the Ballon D'Or gala a few years back, celebrating the award with his team-mates.

The player even revealed that fans that run into him on the streets often mimick his celebration as a sign of respect, which encourages him to keep the signature move alive.

"Later on, people on the street stopped me to yell at me 'Cristiano, siiiuuu', they bonded with me through the celebration and I decided to keep it up," Cristiano added.

It's been over six years since Cristiano's first "Siiuuu". How many more will we watch in the upcoming Serie A season? Don't miss a beat of Cristiano Ronaldo's games with Juventus by visiting Live Soccer TV's Serie A section.
