Laurent Koscielny has signed for Ligue 1 side Bordeaux from Arsenal.
Arsenal have agreed a £4.6m fee with Bordeaux after head coach Unai Emery failed to convince the centre-back to remain at the club.
The French international had stressed throughout the summer he wanted to return to his homeland and refused to go on the club's tour of the United States last month.
Koscielny wanted to leave on a free transfer and thought he would be allowed after nine years of service, something Arsenal refused to entertain.

As you know i engaged with @girondins. After 9 years spent at Arsenal, i took the decision to leave. I have spent wonderful years with this club, nine years during which i learned, evolved, grew up. This experience made me the player I am today. My decision to leave has been discussed for months with my club, my teammates, my coach, and it has been a well thought decision. I see this departure like a new turning point in my life as a player but also in in my life as a man and a family man. However I hope you understand, and in any case i cannot be thankful enough for these years past at Arsenal. I am aware of everything that the club and you supporters have brought to me. But it is time for me to go home so today my will is to join the @girondins. This is a new challenge that I count on taking with determination. Lolo
His first choice was to join Rennes but the two clubs were unable to agree a fee.
It is understood Arsenal are in the market for a central defender following Koscielny's imminent departure.
The club are interested in RB Leipzig's Dayot Upamecano - but it is thought a combination of valuation and the player wanting to stay for Champions League football could make a deal difficult.
Arsenal are also keen on Daniele Rugani from Juventus.
It is thought the move could be easier to do before the window closes as Juventus may consider a loan deal with an option to buy following the arrival of Matthijs de Ligt from Ajax.
Juventus sporting director Fabio Paratici is reportedly already in the UK discussing other deals including Romelu Lukaku's potential transfer from Manchester United.
Arsenal are expected to be busy with ins and outs before the transfer window closes at 5pm on Thursday.
Sky sources understand talks between Arsenal and Nottingham Forest over Carl Jenkinson are continuing.
Both clubs are keen for a deal to be struck before the deadline.
