Leverkusen have won next to nothing, Wolfsburg in the last 15 years have had their only BL, DFB-Pokal, plus Super Cup successes. Both clubs have modern 30.000 capacity stadiums, but struggle to get fans along, especially in Wolfsburgs case. Unfortunately in Germany, there are now so many Munich & Dortmund ‚fans‘ / gloryhunters, with no geographical links to either team and only ever see them on Sky/DAZN.
They were formed in 1904 as a works team, hence their nickname Werkself. Totally different situation to RB Leipzig.
Red Bulls headquarters are in Salzburg, hence their initial activities in football being the takeover of SV Austria Salzburg, with subsequent renaming, rebranding etc.
After that they wanted to get a foothold in Germany, and initiated talks with Fortuna Düsseldorf, St. Pauli & 1860 Munich who all told them to p!ss off. They then purchased the licence of 5th tier SSV Markranstädt, and basically „fairy taled“ their way through to the Bundesliga with industrial amounts of money. The traditional Leipzig clubs, Chemie & Lokomotiv, were on a low ebb at that time and were also anti any Red Bull involvement, so in reality Leipzig a 500.000 city had no team in the top league which was probably the deciding factor.
