Arsenal only released two home and away shirts for the 1999-2000 season. However, a few days ago, Arsenal shirt collector @gkk_collector shared images of the 'Mystery' Arsenal 1999-2000 Champions League third kit, which of course was never used.
Prototype Arsenal 1999-2000 Champions League Third Kit
This is the Arsenal FC 99-00 third shirt, made by Nike.
The Nike Arsenal 1999-00 UCL third jersey is a grey main color, combined with navy logos and details.
The Nike Arsenal FC 99-00 third jersey has a classic look, in keeping with the style of that time with a polo V-neck collar and two cutouts on the sides of the shirt.
As described, the Nike Arsenal FC 1999-2000 third shirt was designed for use in the 1999-2000 Champions League. However, for some reason it was never released and used.
