Premier League holders Chelsea will reportedly make an opening bid of £20m for Arsenal and Liverpool target Pierre-Emerick Aubameyang.

Recent speculation has claimed that Aubameyang may consider his future at Signal Iduna Park, should Marco Reus be up for sale.

The Express now understands that the Blues will step up their interest for Gabon international with a formal bid in the coming weeks.

It is added that the former German champions would wait on all offers before coming to a solution.

Aubameyang has already notched an impressive tally of 23 goals in all competitions for BVB this campaign.
