Some consider Anthony Joshua the best heavyweight in the world.

Joshua can further cement his legacy when he defends his WBA, IBF, WBO and IBO titles this Saturday inside Wembley Stadium vs. Alexander Povetkin.

This marks the return for Joshua to London, as the last time he stepped foot inside Wembley to compete was his 2017 11th round TKO victory over Wladimir Klitschko to begin his reign atop the division.

Since that time, Joshua has earned defenses vs. both Carlos Takam and Joseph Parker in Cardiff, Wales.

Joshua-Povetkin will be streamed live on DAZN in the U.S. as part of the debut for the service in the country. It also airs live on Sky Sports Box Office.

Both successfully made weight on Friday, with Joshua coming in at 246 pounds and Povetkin at 222.

The WBA made Povetkin the mandatory challenger for that title, and Joshua agreed to the bout despite efforts to get himself in the ring with Deontay Wilder and possibly unify all the heavyweight belts. For now, though, he’ll contend with his fellow Olympic gold medalist.

Povetkin, a 38-year-old who captured gold at the 2004 Athens Games, knocked out David Price the same night Joshua fought to his first decision vs. Parker. His only loss since turning pro game to Klitschko in Moscow five years ago.

Joshua might just be the best in the division, but he’s barely known outside of England. All of his bouts have taken place in the country, with only two of his pay-per-view fights generating over one million buys. Those were his fights vs. Parker and Klitschko.

For him to fully achieve superstar-level, Joshua needs to face Wilder and he needs to compete elsewhere. And for that to take place, he has to get through Povetkin first.

If Joshua is successful, and Wilder takes care of business in his rumored bout this December with Tyson Fury, that should put both men on a huge collision course for 2019 in what might be the biggest heavyweight boxing match in years.
