In today's Greatest Kits clash, we have Celtic's away strip from the 2003/04 season and the away shirt from 2009/10.

Away 03/04

Glasgow Times:

The 2003/04 campaign was a successful one for the club from the east end of Glasgow. After losing 3-2 to Porto in the UEFA Cup final the previous season, Celtic finished the 03/04 campaign as winners of the SPL and reached the quarter-finals of the UEFA Cup, knocking out Barcelona on the way.

 

Away 09/10

Glasgow Times:

The 2009/10 season wasn't an especially memorable one for Celtic supporters. Tony Mowbray replaced Gordon Strachan as manager at Parkhead after a stint at West Brom but a series of disappointing results ended with Mowbray being shown the door in March. Neil Lennon was appointed caretaker manager and although Celtic finished the season trophyless, did enough to convince the Celtic board to give him the role on a permanent basis.
