Willian's involvement in our 2-1 Champions League victory over Lille on Wednesday night took him up to a landmark 300 appearances for Chelsea so how about a quiz to test your knowledge on our brilliant Brazilian.
The 31-year-old scored the winning goal in northern France, firing in a volley with 13 minutes remaining to seal our first European points of the season. It is the third time he has marked a milestone appearance with a Champions League goal after notching against Porto on his 100th Blues appearance in September 2015 and at Qarabag on his 200th appearance in November 2017.
Only seven overseas players have now played more games for Chelsea.
To mark the occasion, we have eight Willian quiz questions to answer. Best of luck!
