Underdog Tyson Fury caused a huge boxing upset on Saturday, stunning Wladimir Klitschko with a points victory to snatch the champion's four titles and become the first Briton to hold a world heavyweight crown since 2011.
Undefeated Fury, who improved his record to 25-0 and now has the WBA, WBO, IBF and IBO belts, was never troubled by the 39-year-old Ukrainian who suffered his first loss in 11 years and has already demanded a rematch.
"He's been a great champion, but every good dog has its day," challenger Fury told a 50,000 crowd at Duesseldorf's Esprit Arena.
"Tonight is that start of a new era. I will be the most charismatic champion since Muhammad Ali," he said before serenading his wife in the crowd with a song by American band Aerosmith.
"I worked for six months for this in the gym, it's a dream come true," Fury said while draped in his new world title belts and unable to hold back the tears.
