Manchester United launch Casemiro in the summer transfer window according to TEAMtalk.
The Brazilian has two years left on his contract at Old Trafford with the club also offering a one-year extension.
The Red Devils are hoping to demand a hefty transfer fee for the 32-year-old midfielder as they look to raise transfer funds.
Casemiro remains a key figure for Erik ten Hag at United although the Brazilian appears to be in short supply during the Premier League.
