The Catalan giants announced that a deal had been agreed with Sao Paulo for the 24-year-old's services on Wednesday.

Douglas has now completed his medical and penned terms at Camp Nou until 2019.

Barca have paid an initial 4million to the Brazilian side, with an extra 1.5million due dependant on appearances.

"After a busy day which included his medical...the Brazilian came to the club offices this evening to [put] pen to paper on the five year deal worth 4million Euros, with a further 1.5 million depending on the number of games he plays," read a statement on Barca's official website.

The Brazil Under-20 international joined Sao Paulo in 2012 and was part of the side that clinched the Copa Sudamericana two years ago.

He will provide direct competition at full-back for compatriot Dani Alves.

Douglas is the latest defensive reinforcement for Barca, who had already brought in Thomas Vermaelen and Jeremy Mathieu during the current transfer window.
