Aubameyang has been identified by Chelsea as the man to boost their attack following the departures of Timo Werner and Romelu Lukaku.
They splashed £50million on winger Raheem Sterling this summer, but still lack firepower upfront.
Chelsea’s dire need for goals was exposed during their 3-0 loss to Leeds last weekend.
And the ex-Arsenal forward seemed to confirm his Barca exit with a telling wave to Barca’s supporters at the Nou Camp.
Aubameyang reminded fans what they’ll be missing as he put on a sizzling display in Barca’s 3-3 draw against Manchester City.
Aubameyang simply cracked a smile and offered a wave to the home crowd as the rapturous gesture engulfed the stadium.
His love affair with Barca fans has developed over the course of seven months since he joined in February from Arsenal.
Barca would prefer to keep hold of Aubameyang but need to balance to books in order to register new signing Jules Kounde.
