Oscar, who recently moved to Shanghai SIPG, believes the Chinese league can rival the Premier League one day.
Asked if the Chinese Super League could one day rival the Premier League, Oscar told Sky Sports: "If they continue in this way, maybe yes, because they have lots of good projects."
"Of course the Premier League has higher level of players in the world, but the Chinese guys are very good. They help the new players a lot, and I hope they continue this because I come to help."
"The transfer was good for me, good for Chelsea, good for Shanghai, and I'm so happy to come to the Chinese Super League."
"I think the Chinese clubs spend a lot of money for the players to go to China, to make the league stronger. They made me an offer and I'm very happy to come."
