For the Champions League, Arsenal were drawn with Lens, whose red and yellow stripes clashed with both of the Gunners' kits. When the sides met at Wembley, a one-off navy shirt, with home shorts and home change socks, was worn.1999-2000:
The following year, Arsenal were drawn with Barcelona, who had navy shorts and socks in their early years with Nike. Though yellow versions would later appear, for the trip to the Nou Camp, Arsenal went yellow-white-white.2000-01:
Late 2000 saw Arsenal launch a new navy third strip, worn just three times, all in the Champions League. Its first outing was at home to Sparta Prage with the away shorts and new yellow socks, but it only lasted a half as it clashed with the opposition. 2000-01:
For the trip to Moscow in the second group phase, Arsenal wore the shirt, in long-sleeved format, with the away's normal shorts and socks in a 4-1 defeat.2001-02:
The third and final outing for the shirt was on September 11, 2001, away to Mallorca. The Spanish side were red-navy-navy and rather than pair the new gold shirt with white shorts and socks, the third was used with never-before-seen yellow shorts,2001-01:
A month later, the new away would be paired with the home socks for the trip to Southampton.2002-03:
Another shorts and socks clash in an away Champions League tie, this time against Roma. The home shorts and socks were worn with the away shirt as Thierry Henry scored a hat-trick in a 3-1 win.2005-06:
A rare example of a one-off version of a home strip. For 05-06, the final season at Highbury, Arsenal wore redcurrant shirts of a shade similar to the club's first season at the ground, but were forced to change socks for the trip to Newcastle.2007-08:
For the first time in over 30 years, Arsenal donned white shirts, normally paired with redcurrant shorts and hooped socks. Away to the white-socked West Ham in October, though, a plain redcurrant pair was used.2007-08:
Later that month saw a white version of the shorts (as opposed to the home pair) used for the Carling Cup trip to Sheffield United.2009-10:
In the summer of 2009 Arsenal launched a smart new all-navy away kit, but an early-season trip to Old Trafford meant a change of socks. Despite light blue being the secondary colour on the shirt, white was the choice.2009-10:
The white socks were again seen in the league game at Sunderland, this time with bespoke white shorts too. A beautiful-looking combination, but it doesn't scream Arsenal.2009-10:
Arsenal's third kit that season was in the same style as the away, but white with redcurrant pinstripes and charcoal shorts. The socks were normally white but a charcoal change set were used at Villa Park.2010-11:
A yellow away strip returned in 2010 and against Blackpool one might have expected the navy kit to be utilised. Instead, the only change was that special redcurrant socks were unveiled. The colour-clash didn't seem to bother Arsenal, who won 2-1.2011-12:
The yellow strip was retained as a third for the following season (and 2012-13), though with the special 125th anniversary crest added. Its only outing was in the 4-0 Champions League loss to Milan.2012-13:
Any right-minded Arsenal fan will be hoping that this kit stays on the 'once-worn' list, as it looks terrible. Instead of creating a change sock style for the away game with Manchester United, the red home change set were used.
Arsenal is a club that has always been quite particular about its appearance, so much so that the famous red shirts and white sleeves are never paired with anything other than white shorts, bar a brief period in the 1970s, when a red change set were used on occasion. When it comes to away strips, there are no such qualms about donning replacement pairs of shorts or socks, so much so that, since 1998, there have been at least 16 instances of a kit combination being worn exactly once by the club.
