Chelsea are reportedly set to break club policy by offering Willian a new two-year deal in order to wade off interest from Manchester United.
The Brazilian was strongly linked with a switch to Old Trafford over the summer with Barcelona also courting the flier.
Chelsea ordinarily only offer players over the age of 30 one-year extensions due to their focus on high-energy football.
But Willian, who crossed that age threshold just last week, is in line to land a fresh two-year contract, according to The Sun.
Willian has less than two years left to run on his current deal at Stamford Bridge, worth around £120,000-a-week.
The fresh terms would bring a pay rise for Willian who has now been a Chelsea player for five years.
He fell out of favour under Antonio Conte last term and recently revealed he would have been forced to leave the club should the Italian had remained as manager.
But Maurizio Sarri threw him in from the start on his first Premier League game in charge last Saturday at Huddersfield, a game the Blues won 3-0.
