#6. Dietrich Mateschitz – RB Leipzig/Red Bull Salzburg/New York Red Bulls – £8.48 billion
Dietrich Mateschitz is one of the least popular owners on this list. The Austrian businessman is never far from controversy, probably because he attracts it in three different countries. Sponsorship and advertising has become more and more important in football in recent years but Dietrich Mateschitz has taken that to new levels. Mateschitz owns drinks company Red Bull and not only advertises using his teams but all three of his sides have the product in the name. This has angered football purists for years but Mateschitz still owns all three clubs and is worth an estimated £8.48 billion.
