It's an ever-burgeoning list.
All of them are unwanted entries in Celtic's illustrious European history.
In the past 15 years of European competition Artmedia Bratislava, Braga, Maribor, Malmo, AEK Athens, FC Cluj, Ferencvaros and FC Midtjylland have all put paid to Celtic's Champions League hopes and aspirations.
There was no Hans Christian Andersen fairytale ending here in the MCH Arena for Ange Postecoglou's men tonight.
Just a nightmare show that started with Greek international goalkeeper Vasilis Barlas' first leg howler in the 1-1 draw in Glasgow and continued with the 2-1 defeat in Denmark with goalkeeper Scott Bain once again failing to cover himself in any kind of glory.
Granted, access to the promised football land of milk and honey which is estimated to be somewhere in the region of £30 to 40million to Celtic is never easy.
However, for the best part of a decade Celtic have punched well below their weight and been left to lick self-inflicted wounds.
The Hoops have operated as if the Champions League group stages is some kind of party they have not been invited to with their snotty noses pressed hard against the window looking in.
A closed shop ... well it remains firmly closed to those who dwell in Glasgow's East End for another 12 months.

That's what happens if you fail to prepare, prepare to fail, and all that.
It's the fourth Champions League exit in a row.
Despite a decade of unprecedented domestic dominance Celtic have only qualified for the lucrative stages of European football's premier club competition a paltry FOUR times.
It really is a shocking statistic.
Even Brendan Rodgers failed to make it through to the group stages for the third year in a row of his tenure due to a more prudent spending and signing policy.
That spelt the beginning of the end of the Northern Irishman's reign.
The record is a sad indictment on the club, the board and their failing recruitment policy.
Quite simply, the club never seems to tool up when it matters in preparation for games of this magnitude.
And year upon year the Hoops hierarchy seem content to wave goodbye to a potential £30m windfall because they fail to arm the manager with the necessary tools to compete at the elite level.
Celtic never budget for raking in Champions League riches.
Where there's a Champions League failure down the Celtic Way there's always a Moussa Dembele, a Kieran Tierney, or in this case a Kristoffer Ajer and an Odsonne Edouard to fall back on.
Martin O'Neill and Brendan Rodgers are the exceptions to that rule where money was scattered around liberally.
It is no surprise during both periods that the Hoops achieved some real success in Europe with O'Neill reaching the 2003 UEFA cup final - the club's first European final for 36 years.
Sadly Postecoglou has been cast in the same movie as Gordon Strachan, Ronny Deila and Neil Lennon before him in having to endure an early European exit at the hands of bang-average sides.
Now it has been left to Postecoglou to pick up the pieces from Celtic's European reputation taking another battering alongside Scottish football's co-efficient in the process.
The selling off of prized assets will help soften the financial blow for the men in suits upstairs.
It does nothing to appease the supporters starved of success on the biggest stage of them all.

Postecoglou though should be spared any blame for the latest round of embarrassment on the road in Europe.
The 55-year-old's team lack the basics to compete all over the park - a goalkeeper, a settled defence and attackers of Edouard's ilk for a start.
There is massive surgery needing to be performed on this Celtic team yet the supporters still cling on to the hope of closing last season's 25 point gap differential to Steven Gerrard's title winners Rangers.
Come Saturday at Tynecastle, next season's £40 million Champions League gauntlet will be thrown down.
To this season's title victors the spoils - and automatic access to a business changing sum.
Sadly for Postecoglou, the qualifiers loomed all too quickly in this campaign for a man who was only put in position on June 10, a full four months after Neil Lennon had vacated the premises.
For that reason alone he is exempt from blame in this European debacle as he has spent the majority of his time at the club firefighting in a bid to try and spread much-needed positivity.
The only silver lining for Ange is that Celtic are still in continental competition. They drop down into the Europa League third qualifying round where they will face-off over two legs against Czech side Jablonec.
It was Jock Stein's all-conquering Celtic side who were the torchbearers as the Lisbon Lions set the gold star European standard by which every other side would be measured.
In the halcyon days, Celtic was once a huge name in Europe and feared and respected.
Not anymore.
Perhaps the biggest indictment of all is that when it comes to the Champions League qualifying draws in Nyon every summer, Celtic are now the name on every European team's wish list.
Just ask Artmedia Bratislava, Braga, Maribor, Malmo, AEK Athens, FC Cluj, Ferencvaros and FC Midtjylland exactly why that is?
