Chelsea striker Michy Batshuayi is set to make a loan move to Borussia Dortmund - paving the way for Pierre-Emerick Aubameyang to join Arsenal.
Arsenal have made further progress over the Dortmund striker and are trying to trash out terms.
Dortmund demanded £60m for the striker and Arsenal have gone back with a new approach which includes extra add-ons.
The Bundesliga side wanted to bring in a replacement before giving the deal the green light and had been keen on Olivier Giroud.
