#21 Kalle Sauerland

Promoter Kalle Sauerland is one of the most charismatic characters in the sport. Born in Germany, schooled in England, he has been around boxing his entire life as the son of Hall of Fame boxing promoter Wilfried. He has been instrumental in the World Boxing Super Series and its forerunner, the Super Six, and he's promoted some of the biggest European names in recent years, including Nikolai Valuev, Mikkel Kessler, Arthur Abraham, David Haye and Marco Huck. He has done this while internet fans have dubbed him the 'Colombian Kalle' but also while becoming a hugely popular cult hero, an unusual role for a promoter.
