Chelsea have entered the race to sign Atletico Mineiro right-back Emerson, according to O Tempo.
The defender is one of the hottest prospects in Brazil and two Premier League clubs are taking a close look at him.
Arsenal are tracking the Brazilian, and London rivals could bid £8million for the 19-year-old.
Chelsea have a history of signing Brazilians and have the likes of David Luiz, Emerson Palmieri and Willian at the club. Another Samba man Kenedy is out on loan at Newcastle United.
