The Sun recently reportedly that the Blues are lining up a move for the Gabonese star in the next transfer window.
With the striker's contract running out in 2021, Sky Sports recently revealed that he could leave North London for as low as £20million.
Aubameyang could join the list Arsenal to have made a direct switch to Stamford Bridge and could face the backlash just as Ashley Cole did when he joined the Blues in 20016 after spending seven years in North London.
Cole's move to Stamford Bridge was a swap deal that saw French defender William Gallas move to the Gunners, although the former's move turned out to be more successful.
In recent times, Cesc Fabregas' move to Chelsea was also a big one although he made the switch from FC Barcelona in 2014.
It was revealed by various media in England that Arsenal turned down the first option to sign the 2010 World Cup winner, who helped the Blues win the title in the 2013/2014 season.
