What started as a fun lil edit re Barca, predictably spiraled into a rabbit hole of 90s football nostalgia/history. See below if you're in your mid 30s and have time to kill...
[Edit:] Perhaps specific to Barca, but I think there's an important distinction to be made between supporters based in Catalunya vs. elsewhere. Catalans are notoriously provincial and until the '92 Olympics it would probably be fair to describe them as xenophobic (at least that's how my local teachers described it 10-15 years ago). If I had to guess older Catalan Barca fans probably care A LOT more about La Liga titles than UCL, but for younger fans and those based outside of Catalunya/Spain I'd guess most care about UCL > La Liga. Not sure if the same dynamic is true in Madrid, London, Manchester, Liverpool, Munich, etc. On that note, there's really only a handful of clubs that have won numerous domestic leagues AND some UCLs in the modern era who can even weigh such preferences. MANC and PSG don't have a UCL trophy in the case despite winning a lot of domestic leagues for example. To wit, since the UCL technically came into being in '92-'93, the title winners are as follows (year listed = year final played):
Madrid: 7 (98, 00, 02, 14, 16, 17, 18) [insert barf emoji]
Barca: 4 (06, 09, 11, 14)
Milan: 3 (94, 03, 07) - still weird that this club was considered football ROYALTY so recently
Bayern: 3 (01, 13, 20)
United: 2 (99, 08)
Pool: 2 (05, 19)
Chelsea: 2 (11, 21)
The Field: 6 (Marseille 93, Ajax 95, Juve 96, Dortmund 97, Porto 04, Inter 10)
A few other scattershot thoughts. The first final I can remember watching was the United stunner in 99. If you don't know what happened in that final, OGS's hire makes no sense to you and if you did, it shows you how strong nostalgia is (I kid, OGS has been a surprisingly good manager).
Those early and mid 90s UCL finals are all remarkable for one reason or another. In the inaugural UCL Final in 93, a (presumably) underdog Marseille beat a mammoth Milan side. Marseille certainly had some names like Voller, Deschamps, Desailly, and Barthez (all WC winners), but that Milan side had won the European Cup in 88, 89, would win it next year in 94, and had names like Van Basten, Rijkaard, Albertini, Donadoni, and then the All-timer backline of Maldini-Baresi-Costacurta-Tassotti with Rossi in net to boot.
As aforementioned, Milan got their revenge the next year with many of the same players (and notably Desailly now in the Rossoneri) over a loaded Barca side featuring Romario, Stoitckov, Begiristain, Guardiola, and Koeman. The backline and MF other than Guardiola and Koeman was relatively weak though. I believe Cruyff was canned after this loss, and Laudrup (who didn't start for Barca in the final oddly) left for Madrid the next season, pulling a Figo well before Figo.
In 95, an alltimer Ajax side beat an alltimer Milan side. I bet I'm not the only one here that romanticizes this Ajax squad and considers them formative for their childhood fandom. It's also pretty wild how this final perfectly straddles 2 distinct eras for me, including players I associate with an older era like Blind (Danny not Daley), Rijkaard, Maldini, Baresi, Costacurta, Donadoni, Albertini (you really can't name any of those Milan guys without mentioning the whole lot, with the possible exception of Maldini because he played so. friggin. long.), and that mid-late 90s Dutch golden era I get super nostalgic about including Davids, Seedorf, Overmars, Kluivert, and the de Boers. All of this and I haven't mentioned EDWIN FRIGGIN VAN DER SAR started in net for Ajax (he'd start again for MAN U in 3 UCL finals 20 years later).
Super random tangent, but Van der Sar had a crazy career. He was part of that glorious Ajax golden era, got a move to Juve, got replaced by Buffon, played for 4 years at Fulham, then had a "swan song" of 6 years at United. What weird, long sequence.
I'll come back and finish my thoughts on 96, 97, and 98.
