Oscar has made an impressive start to his career at Stamford Bridge and his Brazil teammate thinks that he is good enough to eclipse the feats of Real Madrid star Ronaldo.
"He is my friend but I don't speak as a friend when I say Oscar can go on to be a better player for the Premier League than Ronaldo was," said Neymar.
"His technical ability is as good as any player in the world and he can score some great goals. He is like Ronaldinho and Rivaldo, a magician on the ball – and even though he has had a good start with Chelsea you have not seen anything yet.
"His game is perfect and he has everything to become the best player in the world in the next two years."
Oscar joined Roberto Di Matteo's side from Internacional in July.
