He was the Arsenal captain and what he did by refusing to join the club on the pre-season tour of the United States of America was nothing short of treacherous.
And according to BBC Sport, the Gunners have now agreed a fee for Koscielny to return to France and join Bordeaux.
Arsenal hope to sign a new centre-back before the Premier League's transfer deadline at 17:00 BST on Thursday, while they retain an interest in Celtic left-back Kieran Tierney despite the 22-year-old Scotland worldwide being injured.
A statement on Bordeaux's official website said: "Laurent Koscielny has officially signed for the Girondins de Bordeaux".
Koscielny is still to discuss personal terms with the club but they are unlikely to be a problem given his desire to leave the Emirates.
Arsenal defender Laurent Koscielny is set to join French Ligue 1 side Bordeaux.
Koscielny could have left with his legacy intact, he could have left with the blessing of the fans but instead, he leaves with his reputation in pieces after going on strike, because Arsenal would not allow him to break his contract.
'We thank Laurent for his contribution to the club and wish him all the best for the future'.
Manager Unai Emery is actively looking to sign a central defender before the English transfer window closes on Thursday.
The France global joined Arsenal in 2010 from Lorient for a reported fee of £8.45 million and went on to make 353 appearances, before being made captain during the 2016-17 season.
Back-up right-back Carl Jenkinson is also in advanced talks to join Championship club Nottingham Forest on loan.
