Anthony Joshua will have a wealth of experience on his side when he faces Jake Paul on Friday night, but that has not always been the case.
In 2017, Joshua stepped up to face Wladimir Klitschko in front of a sold-out Wembley Stadium.
Klitschko arrived in London as a former heavyweight ruler who had competed in 68 fights and who had 53 stoppages.
Joshua endured a mini crisis in the fight, but he rallied brilliantly to register a win in a memorable encounter.
