Player sales will be just as important as incomings for Arsenal during the final six weeks of the summer transfer window.
Whilst the Gunners have been extremely busy so far - signing four players in Gabriel Jesus, Fabio Vieira, Matt Turner and Marquinhos, and closing in on a fifth in the form of Oleksandr Zinchenko - the only high-profile departures have been Alexandre Lacazette, Matteo Guendouzi and Konstantinos Mavropanos.
The Frenchman is leaving as a free agent because his contract expired at the end of June. It means Arsenal have only been able to recoup around £11m in transfer fees, with the latter pair joining Marseille and Stuttgart permanently, respectively, following successful loan spells last season.
