Arsenal are hopeful of confirming the £72m club record signing of Ivory Coast winger Nicolas Pepe from Lille later this week.
The 24-year-old has arrived in London and will have a medical on Tuesday before signing a five-year contract.
The Gunners are also in talks with a number of clubs over the possible departure of 27-year-old defender Shkodran Mustafi.
The German, who is under contract until 2021, wants to stay and prove himself.
Arsenal are keen to find an agreement for a loan or permanent transfer for Mustafi.
Another centre-back possibly heading out of the Emirates is 33-year-old Frenchman Laurent Koscielny, with talks continuing to resolve his future.
