Arsenal may be forced to allow French striker, Oliver Giroud to join Chelsea if they want to land their main transfer target, Pierre-Emerick Aubameyang.
Chelsea will in turn allow Mitchy Batshuayi to join German side, Borrussia Dortmund on loan.
Arsenal are set to pay £60m doe the Garbon international but Chelsea are understood not to be willing to pay £35m asking price for Giroud.
If Arsenal are not able to reach an agreement with Chelsea over Giroud, Aubameyang’s move will rely on Dortmund finding a suitable alternative elsewhere.
All the deals must be completed before 23:00 BST on Wednesday when the transfer will close.
