I personally think that it's a really great story as well and have no problem looking past Red Bull's investment here. There are so many positives worth pointing out like finally having an Eastern European club back in the Bundesliga or their focus on youth development. So far every sport Red Bull invested money in has benefited massively in the long term. Most of the criticism is bullshit anyway and massively blown out of proportion, often coming from fans of traditional clubs that have been mismanaged for years despite a big enough budget to achieve a lot more.
I don't mind at all if it attracts neutrals to the league at all and Leipzig is a beautiful city where a big enough local fan base can develop to support the club and make for a good atmosphere, that's a big difference compared to Wolfsburg or Hoffenheim.
Football is the biggest sport they invested in so far, though. The only comparable case in terms of size is Formula One, a sport which is struggling for years. Football on the other hand produces more money than ever and certainly does not need an additional investor.
I can see the merits of Redbull´s engagement for the Leipzig area and believe that there is great potential for organic growth. I don´t mind that there is no tradition in the club yet as I believe that every club should get the chance to actually develop tradition in the first place.
My problem are with their tools how they artificially boost their growth and that for me goes beyond them bypassing the 50+1 rule which allows them net investments on the level of national top clubs.
This starts with their youth recruitment. I´m still in contact with several scouts from the time I myself contemplated going preofessional and my home club organizes one of the most prestigious U13 tournaments of the country (with usually around a dozen Bundesliga clubs and several International clubs attending). I learned very quickly why RBL is nicknamed "the raiders" around here. The delegation they send to the last tournaments was massive, they had around a dozen scouts with them. RBL is by far the most ruthless recruiter in East Germany, going as far as offering five digit payments to the parents of 12 year olds to recruit them. Officially they have three U13 teams, inofficially it is rumoured to have enough players connected to the club for six teams. Now, their training facilities are top notch, but I see a lot of players falling through the grid at a club with as high ambitions as Leipzig.
The second thing that massively rubs me the wrong way is their relationship to Salzburg. They basically have a breeding ground in a different league (which makes said league fairly uncompetive) and move the players back and forth. The "transfer fees" they pay are nothing more than a farce at is just moving money from one pocket of the company to the other.
Basically, they have not only an edge compard to their peers in terms of higher investment power, but also ways to circumvent the rules of the transfer market.
