Both teams comfortably made it through their semi-finals with 3-0 wins over RB Leipzig and Lyon respectively and will now battle to be crowned kings of Europe - a title which would complete an historic treble for either club.
Bayern have been here and done it all before - only Real Madrid can top their tally of 11 European Cup and Champions League finals, while only Madrid, AC Milan and Liverpool have got their hands on the trophy more often.
It has not been all triumph and glory for the Bavarian juggernauts, though, and they have lost as many finals as they have won in this competition, Juventus being the only team to have been beaten more often at this stage.
PSG know all about despair in Europe's premier club competition; their recent history has been littered by high-profile failures and it remains impossible to consider their Champions League past without thoughts immediately going back to their Neymar-inspired 6-1 defeat to Barcelona in 2016-17.
Now with Neymar in their ranks and beginning to show the decisive influence PSG have been hoping for since his world-record move, the Ligue 1 giants have the chance to finally banish those memories and the hurt of seven successive seasons in which they failed to make it past the quarter-finals.
No French club has ever completed the treble before either as PSG look to become only the ninth team to achieve that feat, but they are facing a Bayern side similarly familiar with a domestic monopoly on titles and with far more experience in Europe.
Sunday represents a tantalising opportunity to make themselves the team to beat, though, and if they are finally able to lift their most coveted prize aloft then there could be no doubting that they are worthy champions.
