Kenedy can play both on the wing at at full-back and is an intriguing addition for Rafa Benitez's side.
The 21-year-old is hoping to really kick on, having been tipped to take the world by storm as a teenager.
He was even compared to Cristiano Ronaldo and spoke of his desire to play at the World Cup with Brazil.
Back in 2013 speaking to Qatar's Al Kass, he said: "I am Kenedy, I am not Cristiano Ronaldo.
"I would love to be part of the World Cup here in Qatar 2022. It will be a fantastic competition in a great country.
“It would be a dream to come back here and represent my country one day.”
Kenedy's first step will be to earn a Brazil international cap. He has two under-23 caps, but needs to step up his game in order to win a senior call-up.
Kenedy's dribbling was the spark for the Ronaldo comparisons. The Mail reported that upon signing for Chelsea, senior players at Stamford Bridge gasped at his tricks.
He is yet to really put it together on a consistent basis in game time, and the loan is just what he needs to he can play regular football.
