Chelsea have completed the signing of Brazil Under-20 international forward Kenedy from Fluminense for an undisclosed fee.
The 19-year-old was part of Jose Mourinho's squad on their pre-season tour to North America, and has now formally completed his move to Stamford Bridge.
Kenedy told Chelsea's official website: "I very much enjoyed my time with the squad during pre-season and I am very grateful to Fluminense for allowing me this opportunity.
"I am very happy to complete my transfer to Chelsea. It is an exciting time for me to join the English Premier League champions and I hope I can become an important player for the club."
Kenedy joins fellow Brazilians Ramires, Oscar and Willian at Chelsea.
