Arsenal have sold defender Laurent Koscielny to Ligue 1 side Bordeaux for a fee of up to 5m euros (£4.6m).
The 33-year-old centre-back had a medical on Tuesday and has returned to France after nine years with the Premier League club.
Frenchman Koscielny had a year left on his contract at Emirates Stadium and the Gunners wanted him to stay.
But he asked for a free transfer and refused to travel on a pre-season tour of the United States.
“We decided to sanction his move to Bordeaux once we agreed acceptable transfer terms,” Arsenal said in a statement.
