Former Chelsea winger Willian could make a sensational return to west London, but to the Blues' rivals Fulham, according to GOAL.
The 33-year-old currently plays for boyhood club Corinthians and has scored just one goal in 44 appearances for the Brazilian outfit.
Willian has 16 months remaining on his deal at the Neo Quimica Arena but has a release clause in his contract which would grant a move back to Europe.
The winger has attracted interest from several sides, including newly-promoted Fulham.
