Chelsea will continue holding talks this week over a deal to sign Barcelona striker Pierre-Emerick Aubameyang, 90min understands.
The 33-year-old only moved to Camp Nou in January after his four-year spell at Arsenal came to an acrimonious end, but he's unlikely to be a regular starter for Barcelona this season following the arrival of Robert Lewandowski from Bayern Munich.
Barcelona have also strengthened in wide areas, bringing in the likes of Raphinha, meaning Aubameyang's hopes of playing as a wide inside forward may also be dashed.
Chelsea, meanwhile, are in desperate need for striking reinforcements after Romelu Lukaku's failed return to Stamford Bridge.
The Belgian has rejoined Inter on loan just a year after leaving the Serie A giants in a deal worth £97.5m, while Timo Werner has also departed west London to rejoin his former club RB Leipzig.
