Striker Deivid Washington will have a Chelsea medical by Thursday ahead of his move from Santos worth £17m.
The 18-year-old Brazilian scored in his opening two games in the Brasileirao, but has made just nine appearances for Santos.
Alongside Moises Caicedo and the incoming Romeo Lavia, Washington would be Chelsea's ninth summer signing. The list already contains multiple forwards, including Christopher Nkunku from RP Leipzig and Nicolas Jackson from Villarreal.
Chelsea are yet to decide whether they will send the Brazilian out on loan or keep him part of the first-team squad.
Washington will also join the many young South Americans recently signed by Chelsea.
