Chelsea's Brazilian contingent will grow in size to five players after they agreed to sign teenager Nathan from Atletico Paranaense on Thursday.
The 19-year-old attacking midfielder has passed a medical, agreed personal terms and will complete his move on July 1.
Nathan has played for Brazil at under-20 level. He also scored five goals in five games at the under-17 World Cup in 2013 before being named in the team of the tournament.
"I am very happy to be joining Chelsea, the champions of England, and I hope I will be able to learn a lot and develop my game," he told the club website.
Nathan joins fellow countrymen Oscar, Willian, Ramires and Filipe Luis in the squad.
