Manchester City have signed Brazil Under-20 international Douglas Luiz from Vasco Da Gama.
The midfielder, 19, has penned a five-year deal with the Premier League club. City's director of football Txiki Begiristain said on the club's official website: "Douglas is an exciting player with great potential. Everyone here is looking forward to helping him develop his talent and progress in the game."
On Friday, City confirmed a deal to bring in defender Kyle Walker from Tottenham in a deal that could reach £50million.
While City have been busy strengthening their squad, one player who looks to be on the way out is striker Nolito.
Sevilla have announced they have reached an "agreement in principle" with City for the 30-year-old Spain international and that he would be undergoing a medical with the club.
If all goes to plan, Nolito will then sign a three-year contract at the Ramon Sanchez Pizjuan.
Nolito became the newly-appointed Pep Guardiola's second signing - after Ilkay Gundogan - when he joined City from Celta Vigo last July for a reported fee of around £14million.
Nolito, who played under Guardiola at Barcelona, signed a four-year contract at the Eithad but found opportunities limited last season and now looks to be on his way back to Spain.
