Willian's future at Chelsea is still very much up in the air, according to his agent Kia Joorabchian, who says the midfielder is determined to "finish his career at a very high level".
Chelsea signed Willian from Anzhi Makhachkala for £30 million ($37m) back in 2013, and he has since racked up 329 appearances for the club, scoring 58 goals.
The 31-year-old has helped the Blues win five major trophies during that period, including two Premier League titles, establishing himself as one of the team's most consistent performers in the process.
