Manchester United have reached a £60m agreement with Real Madrid for Casemiro, with a further £10m in add-ons.
The 30-year-old midfielder is set to sign a four-year contract at Old Trafford, with the option of a further year.
Casemiro’s arrival remains subject to the finalising of personal terms, UK visa requirements and a medical.
The Brazil international is nevertheless set to become Erik ten Hag’s fourth signing of the summer, following the additions of Tyrell Malacia, Christian Eriksen and Lisandro Martinez.
Casemiro will be among the top earners at Old Trafford once he joins up with Ten Hag’s squad but his contractual terms are understood to be heavily performance-related.
While United have dismissed suggestions that he will double his Madrid wages, they will be significantly higher if he helps United qualify for the Champions League.
After winning five Champions Leagues and three La Liga titles during his nine years at Madrid, Casemiro is said to want to test himself in a new environment in the Premier League.
