Chelsea's Brazil midfielder Oscar is closing in on a move to Chinese club Shanghai SIPG.
"It's 90 percent certain," he told Sportv in his homeland. "It just depends on a few bureaucratic details."
The deal would cost the Chinese side a reported 60 million euros (50.25 million pound) according to media reports and reunite him with his former Chelsea boss Andre Villas-Boas.
Fellow Brazilians Hulk and Elkeson play for Shanghai.
A spokesman for the Chinese club would not comment on the reports.
Oscar joined Chelsea in 2012 and has won the Premier League, Europa League and League Cup with the London side.
But after starting the first five league games of the season under new coach Antonio Conte, he has fallen out of favour and been used only four times as a substitute since September.
The progress of Gabriel Jesus and Philippe Coutinho have also limited his international chances and he has yet to appear for the national side under new Brazil coach Tite.
