What could happen today?
In two words; a lot!
Arsenal are still in the market for a central midfielder, as their summer-long pursuit of more creativity goes down to the wire.
Arteta has been a long-term admirer of Houssem Aouar, but Lyon looked to have killed that deal after confirming he will stay with the club.
Elsewhere, Thomas Partey of Atletico Madrid and Jorginho from Chelsea could both be potential arrival on the final day of international window.
In terms of exits, Arteta is busily trying to whittle down his playing squad, with a number of fringe players set for exits.
Lucas Torreira is waiting to complete his move to Atleti, while Sead Kolasinac, Matteo Guendouzi and Shkodran Mustafi could all complete exits.
