Chelsea have set a €15m (£12m) asking price for Pierre-Emerick Aubameyang amid growing transfer interest from FC Barcelona, according to Spanish media outlet Mundo Deportivo.

Aubameyang, who barely played under former Chelsea boss Graham Potter, is seeking to return to Barcelona in the summer.

The Blues are open to selling the 33-year-old striker this summer, though they will not be willing to release Aubameyang from his contract, with Chelsea now setting a £12m asking price for the former Gabon international.

Barcelona and Aubameyang had hoped Chelsea will release him from his contract at the end of the season but the Blues are not willing to do such.
