Casemiro

His full name is Carlos Henrique Casimiro, and he goes by the stage spelling 'Casemiro' on the back of his shirt and across his social accounts. He was born in São José dos Campos, Brazil in February 1992.

His recent Instagram posts include a farewell message at Old Trafford — captions like 'You don't wear this shirt. You carry it' and 'Knowing when to say goodbye' — signalling the end of his Manchester United chapter. He thanked fans, teammates and staff for the time in his career spent at the club.

Casemiro won five UEFA Champions League titles with Real Madrid, making him one of the most decorated defensive midfielders in the competition's history. That European pedigree is a big reason his Instagram audience skews so heavily toward football fans in the US, UK and India.

Casemiro is Brazilian — he was born in São Paulo state and is a long-serving midfielder for the Brazil national team. He's often tagged as Spain-based because he spent nearly a decade living in Madrid while playing for Real Madrid.

Casemiro is a long-time Adidas athlete and wears the brand's Predator boots on the pitch. His feed regularly features Adidas campaigns, including content tagged #createdwithadidas and posts around the Trionda — the official Adidas match ball for the 2026 FIFA World Cup.

His posts in the build-up have leaned heavily on World Cup themes, including the Trionda ball and #thisisbrasil hashtag tied to the Brazilian national team. As one of Brazil's most experienced midfielders, he's a central figure in the country's preparation for the tournament in North America.

Casemiro is married to Anna Mariana, who he met in Brazil before his move to Europe. The couple have two children and she features regularly in his more personal Instagram posts.

He came through São Paulo FC in Brazil, moved to Real Madrid (with a loan spell at Porto) where he won the bulk of his trophies, then joined Manchester United in 2022. His latest posts mark the end of his Old Trafford era.

'Casão' is the affectionate Portuguese nickname Brazilian fans use for him — it's essentially 'Big Case', a play on his name. He uses the hashtag #casão himself on Instagram when posting Brazil-related content.

Casemiro has built one of the largest accounts in world football, sitting in the Mega tier with over 22 million Instagram followers. His engagement rate runs well above the typical sports-creator benchmark, fuelled by a mostly male audience aged 18–34 in the US, UK and India.
