Pierre-Emerick Aubameyang's future at Chelsea is uncertain. The 33-year-old is not getting many opportunities at Potter's side and would like to return to Barcelona.
Furthermore, the Blues have been pretty angry since Aubameyang celebrated Barca's Clasico victory over Madrid.
The board have already started planning the squad for next season. They are counting on Romelu Lukaku to strengthen the attack.
The return of Lukaku could make the Gabonese player's departure easier as Aubameyang has hardly any playing time.
