Chelsea are close to agreeing a deal with Barcelona over the signing of Pierre-Emerick Aubameyang in a move which would see Marcus Alonso move to the La Liga side.
The deal would see Alonso plus around £6.5m go the other way.
Personal terms are expected to be finalised, and Aubameyang is expected to have a medical in London.
No agreement has been reached yet, but all parties are positive, hopeful and willing of getting a deal done ahead of the transfer window closing at 11pm on Thursday.
Aubameyang suffered a minor fracture of his jaw in an attack on his home over the weekend.
The Gabon forward, who is expected to be out of action for three weeks, can resume non-contact training next week.
Chelsea are aware and sympathetic of his situation and it is thought the injury will not impact a potential transfer as talks advance.
