There were many questions sent in for the Brazil international, as part of our exclusive Q&A, which enquired about the celebrations and their meaning.
The fans are clearly aware of the 'six-seven' gesture, which became a craze among youngsters, based around a meme on TikTok and Instagram Reels. Another of the actions, moving his hands towards his nose, was maybe less obvious.
"Honestly, all my celebrations are thought of and decided by my son," stressed Casemiro. "He is football-mad and United-mad, he loves Manchester.
"Every day, when I leave the house, I ask him: ‘What celebration do I have to do?’
"So, the six-seven came from him. Also, this one [motioning towards his nose] is to show that I can smell the goal."
