Bayern Munich have done some great business over the years, and indeed, the club's own initiatives have brought it to the forefront of Europe's top earners. The Bavarian giants have benefited from having little competition around their location in Germany's wealthiest area, but they have emerged not due to help from the federal government or collective television deals as some of Europe's other top-earning clubs have.
Instead, they've forged strong corporate sponsorships, built a loyal and massive fanbase and found good value for money in the transfer market.
Every club has to learn to live with regrets, though, and Bayern are no exception.
