In the last 30 years....
Finished 2nd four times.
Finished 3rd three times

Europa League five times.
UEFA Cup three times.
Cup Winners Cup once.
Scottish Cup winners once.
Top League Scorer twice.
One of only three clubs to not be relegated.
One of only four clubs (inc Old Firm) to play in Champions League.
One of only four clubs to play in all four European competitions.
One of only four clubs to split the Old Firm which we've done twice.
Came within 5 points of winning the league.
Aberdeen have also never been relegated, have four 2nd place finishes and have split the OF, but they have never played in the Champions League.
Hearts have played in the Champions League and all four European Competitions, have split the Old Firm but only have two 2nd place finishes, and have been Relegated twice.
Hibs have split the old firm but have never finished 2nd, have never played in the Champions League and have been relegated twice.
Rangers, well....that could be debated in a hundred aspects til the cows come home.
30 years is just to give us a larger sample size and discount any "flash in the pan" or purple patch. In fact most of that was done in the last 10/12 years so it's not even as if anyone can point to "current wee team harking back to past glories".
Anyone that thinks we should be aiming to stay up and anything else is a bonus, or who lumps us in with the Killies, Livi's, St Johnstone's of the world are absolutely bananas.
There literally isn't a club other than Celtic who can clean sweep us across the board, and no other non-city club that's even in the discussion.
