Chelsea have confirmed that they have completed the signing of Brazilian midfielder Oscar.
The Blues' official website published a statement on Wednesday confirming that the 20-year-old has completed a move to Stamford Bridge from Internacional.
Oscar is a full international for the Selecao and is currently on Olympic duty for his country ahead of London 2012.
He is the latest attacking signing for Roberto Di Matteo, joining Eden Hazard and Marko Marin as Chelsea look to improve on last season's fifth-placed finish.
Oscar may make his debut for the Blues against Wigan Athletic on Sunday, August 19.
