One of the most iconic clubs in the world, lots of Celtic players over the years have become legends.
Indeed, from the famous 1967 European Cup winning team containing icons such as Billy McNeil and Jimmy Johnstone to the ludicrously prolific Henrik Larsson in the late 1990s and early 2000s, this is a club where history is made.
Still, like with any team across the world, there are a number of players who don't quite get to that level.
Sometimes, moves just don't work out. Either your big signing doesn't quite turn out as hoped or that promising young talent is not quite the superstar he once looked.
That, sadly, is just part of football.
