The Brazilian midfielder flew into Manchester this afternoon and travelled straight to Old Trafford to complete his transfer from Real Madrid.
He was introduced on the pitch ahead of kick-off in what was bound to be a special moment for him and fans during the build-up to one of our biggest games of the season.
In addition, supporters also had the chance to celebrate the success of England's Euro 2022-winning Lionesses from United – Mary Earps, Ella Toone, Alessia Russo and our recent signing from Arsenal, Nikita Parris.
Casemiro, who has played 63 times for Brazil, becomes the latest signing during this transfer window, joining Christian Eriksen, Tyrell Malacia and Lisandro Martinez, as Erik ten Hag continues to strengthen his first-team squad.
