The Gabon international has been prolific again this term, already netting 17 goals in 19 matches in all competitions.
Reports emerged on Monday indicating Liverpool are weighing up a move for Aubameyang should Daniel Sturridge decide to leave Anfield.
Aubameyang has proved to be rather high-maintenance at Dortmund and he was sent off in the 4-4 draw with Schalke over the weekend.
And according to the Daily Mirror, Chelsea are one of a handful of sides that have been informed of his availability.
The Mirror also report that he is at loggerheads with some of his team-mates and angered his club by taking part in an unauthorised video shoot.
Antonio Conte will be eager to increase his firepower when the transfer window reopens.
Although Alvaro Morata has collected eight Premier League goals, he appears to have struggled at times with the demands of English football, while back-up Michy Batshuayi is sidelined through injury.
As far as Liverpool’s interest is concerned, Aubameyang’s brother may have provided the death knell.
He said: “The thing is over now. He just wants to win and score many goals.
“He is still completely in Dortmund with his head.”
