Willian said he eventually wants to play in MLS once his career winds down in Europe.
"I have plans to stay in Europe and try to play here maybe for three or four more seasons. I believe I can still perform on a high level. After that, when I will be 35, 36 years old, I intend to go to the United States and play there," said Willian.
The 31-year-old recently signed a short-term extension to stay at Chelsea through the end of this season.
Willian added that he prefers a move to MLS over a return to Brazill.
"I don't rule out returning to Brazil, it is my country and my culture. But returning to Brazil would not be my first choice if I leave Europe. I have the wish to play in the United States also because of my family, being able to live in the United States would be good.
