As a question to Bayern fans, how do you guys see the influence of LVG compared to Pep? I've heard a few times that LVG was seen as the real pioneer for Bayern becoming what they are now - maybe pioneer is the wrong word - but I hadn't realised his stint was seen as so important given he didn't win as much and it was relatively short.
Not a Bayern fan, but at least I followed them closely:
LvG did give Bayern a style and identity which they didn't have in the previous years, they were in a way directionless and confused. And he did that by promoting and relying on a strong core of young players ("Müller always plays"), and also allowed other players to step up into leading roles (for example Schweinsteiger). He had his flaws, but his natural arrogance just fit the club well (on the other hand he himself acknowledged that there is never enough space in any club for both his and Uli Hoeneß' ego). So he really set the club on track for a decade.
Heynckes after him carefully adjusted and tuned the foundation LvG had left him, also the youngsters LvG had brought through really matured into reliable consistent top performers, which lead them to win the treble and break records in Heynckes' final season.
Pep did continue mostly like Heynckes - LvG's legacy was well in line with Pep's philosophy, so he as well carefully maintained the team and kept them performing on that ridiculuously high level in the league. But unlike Heynckes he failed repeatedly to keep the performances up until the very end of seasons. Which is why he did not break Heynckes league point record and why he did not reach a single CL final.
Actually when Pep left it was more the case that Bayern slowly shifted away from that possession/position play style that they used from LvG to Pep and slowly turned into a more physical, transitional team which peaked under Flick and won the sextuple in 2020.
Pep's legacy at Bayern is that he is the most reliable league winner in the history of the league. But that's all, he didn't bring a new style, he didn't break (meaningful) records, he didn't win the biggest titles. LvG reached a CL final with a squad that should have been far to young to win it (and lost), Pep didn't reach a final even when that squad had peaked.
