Rafinha has agreed to sign a new five-year contract at Barcelona, the Spanish champions have announced.
The full-back is set to miss much of the remainder of this season with a torn anterior cruciate ligament but the club confirmed on Monday that he will sign a new contract with a €75 million release clause.
The Brazil international came through the youth ranks at Camp Nou and broke into the first time in 2011 via a loan spell at Celta Vigo.
His initial deal was due to expire in June 2016, but the 22-year-old will now remain under contract until 2020.
During his time with Barca, Rafinha has won the Copa del Rey in 2012 before forming part of the treble-winning side under Luis Enrique last term.
