Chelsea boss Frank Lampard has spoken of his "love" for Willian, but he said it falls on the club to decide whether to hand him a new contract.
Willian is in the final year of his deal at Stamford Bridge and will be free to negotiate with foreign clubs in January.
Per Goal's Nizaar Kinsella, Lampard said of Willian's contract: "The word isn't 'no-brainer' because I can't get involved in the money. That's up to the club to do. But everyone sees how much I'm relying on him, and picking him and in what he is producing, I love him at this football club.
