If you're one of those people that thought George Kambosos Jr's knockdown of Teofimo Lopez in the very first round was a "lucky" shot, then you'd be sorely mistaken.
New footage has emerged online showing the Australian working on that exact punch during a training session months before fight night.
Close your eyes and swing for the fences? No chance.
In a clip uploaded by BOXRAW, Kambosos Jr can been seen hitting pads with one of his coaches.
He then practises a devastating overhand right, which is the exact same shot that sent rival Lopez crashing to the canvas in the first three minutes of their world title fight.
"I set him up beautifully. That was not a lucky shot," Kambosos Jr says in the video.
"That was many months of setting that shot up. Working on that shot."
And, as we all now know, those months of rigorous training sessions after a number of cancellations ended up paying off.
Despite the frustration with countless postponements, Kambosos Jr kept his head switched on a remembered everything he worked on in the gym.
The victory at Madison Square Garden to clinch the WBA, IBF, WBO and WBC 'Franchise' belts will undoubtedly go down as one of the greatest moments in Australian boxing history.
Now, though, Kambosos Jr is a wanted man.
Some of the division's biggest names have already called him out with an undisputed lightweight title fight against Devin Haney now looming.
"It was such a brilliant performance, so I think it's disrespectful to say that George Kambosos is an easy touch," promoter Eddie Hearn told Boxing Social.
"He just beat Teofimo, who beat Lomachenko. So George deserves respect and credit, and right now, he's the man. I don't mind saying it.
"Devin Haney is my man, but massive respect for George and his dad. But right now, George is the man; he has the standout victory in the division.
"And this win for Devin this Saturday will be another standout victory, and then the two must meet."
