In today's Greatest Kits reader poll, we're pitting Celtic's away kit from the 2000/01 season up against the away shirt from 2005/06.

Away 00/01

Glasgow Times:

The summer of 2000 was quite a time to be Celtic supporter. Martin O'Neill, one of the up-and-coming managers in British football, had just arrived and Celtic splashed the cash accordingly. Chris Sutton, Alan Thompson and Neil Lennon all followed O'Neill to Glasgow from England and the team went on to complete a clean sweep of the three domestic trophies. Not bad at all for a debut season in Scottish football.

Away 05/06

Glasgow Times:

Another manager's debut season in the Parkhead dugout, but this time it was Gordon Strachan. Strachan couldn't quite repeat O'Neill's feat of a Treble, but secured a league and League Cup double with help from new signings like Maciej Zurawski and Shunsuke Nakamura.
