Real Madrid have taken up their option to turn the loan deal for Brazil international Casemirofrom Sao Paulo into a permanent transfer for a reported fee of €6 million ($7.9 million, £5.1 million)
"Real Madrid have taken up their option to buy Carlos Henrique Casemiro, that will tie him to the club as a first-team player for the next four seasons," a statement on the club's website said on Monday night.
The 21-year-old, who has five caps for his country, spent last season on loan at the Spanish giants, where he played the majority of the season with Real's youth side Real Madrid Castilla in the Segunda Division.
Casemiro, however, impressed on his debut with the senior side against Real Betis in April and is expected to fill the gap left in the squad by the return of Michael Essien to Chelsea after the Ghanaian's season-long loan deal came to end.
