Oscar believes that the Chinese Super League is capable of reaching the same levels of the Premier League.
Brazilian midfielder Oscar secured his move to Shanghai SIPG earlier this month for around £52million.
The 25-year-old, who is likely to earn around £500,000 a week in China, was criticised for moving by Sky Sports pundit Jamie Carragher.
But Oscar has explained his reasons for departing Stamford Bridge in an interview with Sky Sports.
“The transfer was good for me, for Chelsea and for Shanghai,” he said.
“I’m so happy to come to the Chinese league.
“The Chinese clubs put a lot of money for the players to go to China and make the league more strong.
“They offered me and I was very happy to come.”
He added: “Of course, the Premier League has the highest level of players in the world.
“The Chinese players are very good, they help their new players a lot. I hope they continue this because I come to help.
“If they continue in this way [recruiting stars from Europe], then maybe yes [it could be as good as the Premier League] because they have a good project.”
