In the space of just five years, Anthony Joshua has risen from a little known GB Olympian to the heavyweight champion of the world - it's an incredible journey.
Fighters who perform well at the summer games certainly aren't guaranteed success in the professional game, yet AJ has transcended the formats with ease.
The 27-year-old's record stands at a formidable 19-0 - all by knockout - and has the WBA and IBF titles to his name after defeating the mighty Wladimir Klitschko in April.
Despite having already been a world champion, victory over Dr. Steelhammer was the true vindication that AJ is both the real deal and a man who can mix it with the veterans.
Furthermore, what better way to stage the occasion than in front of 90,000 people at Wembley Stadium. The public responded too with a full house under the famous arch and the obliteration of the British Box Office record.
A savage uppercut in the 11th round kick started a series of knockdowns with the stoppage eventually arising and Klitschko slumping out into retirement.
However, it's easy to forget that that historic day wasn't the first time AJ fought at Wembley Stadium.
In 2014, the fight on everybody's lip was the rematch between George Groves and Carl Froch which would take place at the famous venue on May 31.
Joshua had the chance to announce himself to the world in being drafted on the undercard that day, fighting Matt Leg in his sixth professional bout.
At the time, the fight wouldn't have appeared significant but those in attendance certainly didn't forget AJ's ruthless debut on the big stage.
Despite receiving a hearty right hook in the opening seconds, Joshua began to style on his veteran opponent with a series of rapid combinations. Legg knew he couldn't outbox the Olympic champion so tried to unleash a chain of power punches.
After just 76 seconds, though, Joshua unleashed a brutal uppercut that Legg simply couldn't recover from. Check out the fight (and trust us, it won't take you long) below:
It's remarkable hearing the commentators hypothesise as to whether Joshua will be a world champion one day.
Absolutely destroying Legg in just a minute showed his power but only now can we truly look back and see the early signs of greatness.
Roll on October 28 and Kubrat Pulev.
