Barcelona have signed Brazilian midfielder Arthur from Gremio in a deal worth £35.5m (40 euros).
The 21-year-old put pen to paper on a six-year contract with Barcelona. The deal includes a buy-out clause of 400m euros for the player.
The transfer was announced just a day after fellow countryman Paulinho left the Camp Nou to rejoin Chinese club Guangzhou Evergrande on a season-long loan.
According to BBC Sport, "Arthur joined Gremio in 2010 from lower-league side Goias Esporte Clube and made his first-team debut at the age 18 under former Brazil manager Luiz Felipe Scolari in 2015."
The youngster helped Gremio win Brazil's equivalent of the FA Cup, the Copa do Brasil, in 2016 and South America's Champions League - the Copa Libertadores - in 2017.
He has scored six goals in 66 appearances for Gremio.
