Anthony Joshua vs Wladimir Klitschko, the 2017 blockbuster at London’s Wembley Stadium with an attendance of 90,000, was a heavyweight title‑fight classic. With the IBF, vacant WBA (Super) and IBO belts on the line, Joshua at 27 and Klitschko at 41 gave the bout a real sense of prime versus experience, and boxing fans were not disappointed.
