Chelsea boss Antonio Conte has claimed that Oscar's "situation" at Stamford Bridge "will be clearer in the next few days".
The Brazilian international has struggled to win a spot in Conte's first XI since the Italian switched to a 3-4-3 formation, and it is understood that Chinese Super League side Shanghai SIPG are prepared to pay £52m to sign the midfielder in January.
When questioned on the 25-year-old's situation on Friday afternoon, Conte said that an announcement on the midfielder's future would follow in the coming days.
"The situation with Oscar, I think it will be clearer in the next few days," Conte told reporters. "Oscar started the season very well with us when we played with a 4-3-3 and he played very well.
"Then when I switched to another system, another formation, he didn't play a lot. But I always counted on him because Oscar is a really good player."
Oscar joined Chelsea from Internacional in the summer of 2012 and has scored 38 times in 202 appearances for the Premier League outfit.
