Anthony Joshua is at the top of his game in boxing but has been showing his fine skills since a very young age.
Much before he broke onto the scene as one of Britain's greatest to fight within the ring, the two-time heavyweight champion punched an opponent so hard his head guard went flying off.
As AJ and his opponent came together close to the ropes, rapid firing of quick hits from close range forced the protection gear off his unknown opponent.
The video emerged on Twitter shortly after Joshua called for Tyson Fury to “come and fight me”.
Joshua, 30, has three of the four world heavyweight titles while his fellow Brit Fury holds the other.
No fighter has ever held all four at heavyweight and the duo both have contracts in place to take on other people next.
But Joshua called for Fury to make space for an all-British showdown with the belts on the line.
He said: “Logically, to prove yourself as number one, I have to fight Tyson Fury. He has to fight Anthony Joshua.
“If you really want to say you're number one, come fight me. Let's get it on. I've got the rest of the belts so it only makes sense.
"I'm the unified heavyweight champion of the world, he's the WBC champion. What will it prove, me and him fighting? There will be one dominant figure in the heavyweight division that will have all of the belts and become undisputed."
He added: “It would be amazing to tell Pulev 'I think it's best if you step aside for now' and to tell Wilder 'we have bigger fish to fry'.
"That fight [with Fury] needs to happen because there will never be another time like this again.”
