Chelsea have asked Marseille to pay just €6million for striker Pierre-Emerick Aubameyang.
The Blues are unwilling to allow the 34-year-old leave as a free agent this summer.
Aubameyang has already being offered to Saudi Arabia.
According to Fabrizio Romano, an agreement has been reached on a three-year contract between the striker and Marseille. However, Chelsea are seeking a fee of €6 million (£5m/$6.7m) from the Ligue 1 side.
Aubameyang’s potential move to the south of France represents an opportunity for the Gabon international to reignite his career after a disappointing spell at Chelsea.
Marseille, on the other hand, see him as a valuable addition to their squad. Chelsea’s insistence on securing a fee reflects their desire to recoup some of the investment they made on Aubameyang, who arrived for £12 million (£10m/$13m) from Barcelona last year.
