The Chinese Super League is set to welcome another star, with the Brazilian midfielder claiming his move to Asia is all but completed

Chelsea midfielder Oscar says he is on the verge of completing a transfer to Chinese Super League giants Shanghai SIPG.

Reports in England have claimed the Brazil international is set to reunite with former manager Andre Villas-Boas after Chelsea accepted an offer said to be worth up to €60million.

And the 25-year-old is now expected to complete the move when the transfer window opens after claiming that the deal is all but finalised.

Oscar and the top Chinese transfers

"It's 90 per cent certain," he is quoted as telling SporTV. "It just depends on a few bureaucratic details."

Oscar has won the Premier League, the Europa League and the EFL Cup since joining Chelsea from Internacional back in 2012.

The attacking midfielder was a key part of former boss Jose Mourinho's plans, particularly during their title-winning campaign of 2014-15, but he has found his opportunities limited under Antonio Conte.

Oscar started all five of Chelsea's opening Premier League games this season but has been restricted to just four substitute appearances since September, with Conte having revitalised his side's form during that time by using a 3-4-3 system.

He is expected to become the most expensive signing in CSL history, with his transfer fee anticipated to eclipse the reported €55.8m paid by Shanghai to sign compatriot Hulk from Zenit in June.

Inter Milan had been strongly linked with a bid for Oscar last summer and, following the close of the summer transfer window, Conte expressed his delight that the player remained part of his plans.

“Yes, absolutely,” said Conte when asked how pleased he was to have retained Oscar's services ahead of his side's clash against Liverpool at Stamford Bridge, which was his last Premier League start.

’China bound to tempt Messi & Ronaldo’

"There are many speculations from Italy, of course, but I'm very glad to have him and that he stayed. He's in my plans, in Chelsea's plans.”

Ahead of last month’s game at Middlesbrough, where Oscar featured as a late substitute, Conte also reiterated that the South American’s future was with Chelsea.

"His future is Chelsea, full stop," he said.

"For me he is an important player in the squad. He's in good form and a great player."

Speculation has recently linked Inter with a fresh move for Oscar, with Juventus and Fenerbahce also rumoured to be interested, but it appears the money being offered by Shanghai has persuaded Chelsea to cash in.
