Chelsea and Pierre-Emerick Aubameyang's representatives are continuing talks about a potential transfer.
The Gabon international may be in line for a return to the Premier League this summer.
Aubameyang left Arsenal for Barcelona in January, and enjoyed a good second half of the season for the Catalans.
However, the signing of Robert Lewandowski has pushed him down the pecking order with Barca.
Transfer expert Fabrizio Romano reports that his agents are talking to Chelsea, even though Auba would prefer to stay at the Catalan club for at least another season.
The 33-year-old could cost Chelsea €30 million, despite signing for free for Barca six months ago.
