The South American playmaker spent four-and-a-half years at Stamford Bridge before heading to China in the winter window of 2017
Brazil international playmaker Oscar has reiterated that he still wants a return to Chelsea, with the South American eager to test himself in Europe again and chase down Champions League glory.
The 29-year-old moved to Stamford Bridge in the aftermath of the European triumph for the Blues in 2012 and would spend four-and-half years in west London.
He departed for China in the winter window of 2017, where he is now with Shanghai Port, but the prospect of retracing his steps when becoming a free agent in 2024 is one that still appeals.
