Bordeaux have been holding talks to sign the wantaway centre-back, with Arsenal demanding a fee for the defender, despite his desire for the remaining year on his contract at the Emirates Stadium to be terminated.
Arsenal captain Laurent Koscielny is set to complete a move to French side Bordeaux in a deal worth £4.6million.
Now Koscielny is close to ending his nine-year association with Arsenal. The Sun have claimed that move is close, with a medical scheduled for Tuesday.
This summer Koscielny refused to go on the club's pre-season tour to the United States and put in a request to have his contract terminated to allow him to join another club, which was rejected by the Gunners.
Both clubs are keen for a deal to be struck before the deadline.
The young French centre back is highly regarded and according to the Guardian, the U21 French worldwide is the Arsenal's prefered central defender target.
Sokraitis and Shkodran Mustafi are the first-choice for Arsenal at centre-half, while the club signed William Salbia from St Etienne earlier in the summer, but loaned him back to the Ligue 1 outfit.
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 hard.
The Gunners are also in advanced talks over the sale of English right-back Carl Jenkinson, 27, to Championship side Nottingham Forest.
