Ach, sorry I missed this chat. Love this kinda stuff. And I get exactly what you mean:
It's like all three times we've played Sporting in Europe, they've come away with a decent result from the Ibrox first leg and then we've won the tie after some serious drama in the Lisbon return - and that's three ties taking place over the course of forty years: in 1971, 2008 and 2011.
As you're saying above, we've now met PSV Eindhoven four times in Europe since 1978-79; they've only lost once at Ibrox: we've never lost in Eindhoven. Nuts.
Last season Borussia Dortmund became the team we've played most often in European competition: five different ties (if, that is, for the sake of this argument, you want to treat the home and away meetings in a group stage as a "tie") and, from the 1966-67 Cup-Winners' Cup - when they were holders - to last season when they were the second-best side in one of Europe's top five domestic leagues, they've never won at Ibrox, we've only lost once in the Westfalen, and the only time they've put us out was on penalties after a last-minute equaliser.
Bayern: Five ties but one of them was a final (so only a single match, meaning we've played them in nine individual legs as opposed to ten versus Dortmund): We've only eliminated them once (arguably our greatest ever result, in 1972) but twice they've had last-minute equalisers to snatch a draw at Ibrox and we've never conceded more than once in Bavaria... and had three draws over the 90 minutes there, including the one where we didn't concede until extra time, in the 67 CWC final in Nuremberg.
Inter we've met three times, them always doing better over the two games but without ever winning at Ibrox (this includes our pre-Souness Revolution mid-eighties team up against an Inter with two strikers who had/would scored/score in the World Cup final!) and, as ye say, the parallels in our two ties with Villarreal - either side of us being bloody liquidated - are frightening.
Of course, there's plenty evidence to say it's all bunkum - off the top of my head, Standard Liege, Gornik Zabrze, Leeds, Sevilla and Saint-Etienne are clubs we've lost one and won one tie against over the decades so no "historical pattern" there.
But, like how the fact we ARE a European trophy-winning club definitely effects our mindset going into European games (as a team and a support), I think there is definitely a belief formed (negative or positive) by the prospect of playing a club you have famous previous with.
So, like you're saying, Buster - with Ajax we're done but with Liverpool and Napoli it's time to set the right tone.😄
