Borussia Dortmund striker Pierre-Emerick Aubameyang is encouraging interest from Chelsea.
The Sun says Aubameyang is keen on a move to England and has been offered to the Premier League champions.
Blues boss Antonio Conte has still identified Real Madrid's Alvaro Morata as his No 1 target to succeed Diego Costa, who has been told to stay away from the club's Cobham training ground ahead of a switch to Atletico Madrid.
But France-born Aubameyang has been made available to clubs around Europe and in the Far East — and Germans Dortmund believe he could be set for a move to China.
AC Milan and Paris Saint-Germain have also been interested.
