Out with the old guard, in with the new.

Tyson Fury defeated Wladimir Klitschko to become boxing’s new world heavyweight champion on Saturday, taking home a unanimous decision after 12 grueling rounds.

Fury told the media he “looked in Klitschko’s eyes, and I knew I could win.”

Klitschko took to Twitter to congratulate his opponent.

The victory gives him four belts, making him the WBA (Super), IBF, WBO, IBO and The Ring unified heavyweight champion. The 27-year-old improves to 25-0-0 while Klitschko, 39, falls to 64-4.
