Pires was part of the famous Arsenal side which went through the entire 2003-04 season without losing a game en route to the Premier League title.
And the former France international was reunited with a handful of his ex-team-mates on Monday night ahead of the first screening of a new documentary documenting that memorable campaign.
Pires shared the photo above of himself with Jens Lehmann, Pat Rice and Martin Keown and wrote: “#invinciblesdoc #keown#rice#lehmann”
The former midfielder then posted the photo below with Lauren, Sol Campbell and Ray Parlour.
‘Invincibles’ is set to air this week and features interviews with the likes of Arsene Wenger, Thierry Henry, Lehmann, Sol Campbell, Parlour and Martin Keown.
The documentary will debut on Sky Sports 1 and 5 on Wednesday 25 February at 22:15 GMT, with a replay scheduled for 18:00 on Sunday 1 March.
