Real Madrid have completed the permanent signing of Brazilian starlet Casemiro on a four-year deal.
Casemiro spent last season on loan with Madrid Castilla, Real's reserve side, while also making one appearance for the senior side in La Liga under former boss Jose Mourinho.
The 21-year-old signed a deal to join Madrid yesterday after the Spanish giants met his £5.1m release clause with Sao Paulo.
A short statement confirming the deal on Real's official website read: "Real Madrid CF have used their purchase option to buy Carlos Henrique 'Casemiro'.
"As a result he will be a first team player at the club for the next four seasons."
The midfielder is Madrid's second signing of the summer, following Dani Carvajal's decision to rejoin from Bayer Leverkusen last week.
