Arsenal forward Alexandre Lacazette sent Laurent Koscielny an emotional farewell message on Twitter.
Koscielny joined Bordeaux for a fee of around £4.6m, after making 353 appearances in all competitions for Arsenal.
In a message posted in both French and English Lacazette said: "Thanks Captain, it's been a pleasure and an honour to play 2 years alongside you. #respect," and also included a picture of the two embracing on the pitch.
Some Arsenal fans reacted with disappointment to Lacazette's post, with supporters not happy with how Koscielny went about pushing through a move away from the club.
