Gladbach and Bayern rose together to the Bundesliga in 1965 and first split paths only after Gladbach’s first relegation in 1999. No current Bundesliga side have historically given Bayern a tougher home away day than Mönchengladbach. Bayern have lost more away matches there than at any other club, have conceded more Bundesliga goals to Gladbach than to any other opponent, and as of December 2019 had suffered 21 defeats in Mönchengladbach. There have been wild opening phases, title-deciding games, drunken Bayern defeats after European finals, Lewandowski’s one genuinely awkward opponent, and a long list of players who wore both shirts.\n\nFor Gladbach fans, these Bayern matches have long carried almost derby-level intensity.
