Despite a successful six-and-a-half-year period at Stamford Bridge, Willian has been allowed to enter the final 12 months of his deal.
The 31-year-old told Yahoo Sport: "I have stated several times my wish is to stay at Chelsea. I like the club very much, I feel very welcomed here, as well as my family, and we love living in London.
"However, I'm in the middle of the season and I try not to think about it so as not to lose focus on the field. My agent and the club are talking and I hope we can have some good news soon."
Willian has established himself as a first-team regular under Frank Lampard, making a total of 17 starts in the Premier League and Champions League.
