Cristiano Ronaldo first popularised the Siu celebration during his time at Real Madrid, shouting a drawn out version of the Spanish word for yes as he leapt and landed facing the crowd. The celebration followed him to Juventus and Manchester United and became one of football's most copied trademarks. Clips of the chant were remixed into short music edits on social media, where fans paired the build up and shout with goals, wins and ironic triumphs, keeping it in constant circulation online.
