Shanghai SIPG's general manager has said Oscar's decision to leave Chelsea was due to his lack of playing time.

Oscar will be paid up to £20 million per year.

"Oscar has fallen out of favour with Conte because he has no place in Chelsea’s 3-4-3 formation," said Sui Guoyang.

"It played a key part in his desire to leave. He felt terrible to sit on the bench and not be involved. He is so young.

"Oscar wants to come back to the Brazil national team. Some of his compatriots play in the CSL and they still get called up to the national team. So it helped him to make the decision to move to China.

"And of course, the appointment of [ex-Chelsea boss] Andre Villas Boas is a plus. Oscar knows we are an ambitious club."
