Formerly known as SSV Markranstädt, league regulations prevent the club using the Red Bull brand in its name, so it settled on RB Leipzig instead; but there is no ambiguity over the power driving it forward, with a reported planned $128 million investment to take the club to the Bundesliga by 2017.
After promotion in its first season, followed by two years in German football's fourth tier, its plans look to be on track as the club prepares to contest the playoffs for another promotion in June.
The club's stadium, the impressive 45,000 capacity Red Bull Arena, is certainly ready.
"We accept this rule," said RB Liepzig's managing director Ulrich Wolter, referring to the "50+1" rule.
"The intention of the rule is to secure the league's integrity against short-term investment, I think everyone understands that."
However, Wolter is frustrated at the resistance to RB Leipzig's owners.
"Red Bull is not a Russian oligarch, or an Arabian sheikh," he said. "We've shown elsewhere that we're about a strong, sustainable investment and commitment.
"Why is our way the wrong way? What is the difference between our approach and a club with 50 different sponsors delivering the same thing?"
Even so RB Leipzig's new investors have encountered resistance.
The pitch at its former stadium was attacked with weed killer not long after the takeover, and fans of other clubs can be less than welcoming.
"It's getting better," says Wolter. "We're proud of our family and spectators. We don't have 'ultras' and we don't need them. It's a friendly family atmosphere here, with men, women, children, pensioners, it's a different way."
Germany's often raucous fans are, however, part of the fabric of the Bundesliga experience.
The biggest obstacle to change in Germany may come from those very supporters, many of whom view the English Premier League with disdain, given that they see themselves at the center of a club's structure.
The Bundesliga boasts some of the world's finest stadia, and its commitment to safe standing areas has helped enable clubs to keep prices low, as well as creating the boisterously vibrant atmosphere that characterizes top-flight games.
But while the cheapest season tickets represent superb value, if fans turn up on match day looking for tickets then the story is rather different. "People are always talking about cheap tickets, but it can be misleading," says Dykes.
"Of course standing tickets are cheap, as you would expect; but once these go, and they're usually in demand, the ticket prices at the top end are broadly comparable to those in England."
In fact, at $88 the most expensive match-day ticket for Bayern is the same as that at Manchester City, for example -- and $9 more expensive than at Manchester United.
This year, partly in response to incidents of crowd trouble at games, there have even been whispers that the prized standing areas could be abolished.
"Standing is vital to low ticket prices, but also the atmosphere and the overall product of German football," said a skeptical Dykes.
"The league realizes that and I can't see the standing areas being given up. It would be difficult under German federal law to 'ban' them anyway, so I just can't see it happening."
The worry for other Bundesliga clubs must be that the success of Dortmund and Bayern could put them out of sight in the financial and playing stakes; last year Chelsea received an estimated $77 million from winning the Champions League, while beaten finalist Bayern pocketed $53.65 million.
Youth and prudence
However, the notion that a couple of teams might dominate their league is not confined to Germany.
"Spain's that way, the last three or four years the third or fourth place team, they still play Champions League and they're 30 points behind," said Hargreaves.
"A lot of people in Germany love Bayern and love Dortmund, in the same way as people (in England) love Manchester United or Chelsea," he added, "but there are a lot of people who root for the underdog as well. So I think, in a way, it's a fair balance."
And Dykes remains unconvinced that a tipping point has been reached.
"It's too early to be talking about a duopoly," he said. "Success comes and goes. If we're still talking about those two in a few years' time, or Bayern are still miles ahead, then it would be a worry.
"People look at that possibility and of course it could be bad, but why would it happen? Bayern have always spent big; Dortmund is an exceptional team, but where will they be in three years?
"Players lose form, get injured, things can change quite quickly. I'm not worried."
For Wolter, the key to success lies in a combination of youth and prudence.
"You look at a team like Freiburg, they have a good academy, a good coach; it's still possible (to be successful). The new television contract has also given clubs more money ... and these academies are profit centers," he says. "But it's not all about money. It's also about education, good background work."
Nevertheless, as Bayern and Dortmund take the field at Wembley, some may be wondering if, as well as a moment of national pride, this game might also mark a less welcome watershed in German football.
