Naoya Inoue unleashed a string of punches that left the referee with no decision but to step in and stop the fight after downing Nonito Donaire before the second round finished.

The Japanese boxer already has his sights on his next move, declaring he wants to become the undisputed bantamweight world champion.

All he needs to become the undisputed champion is the WBO belt which is currently held by Paul Butler. That means his next moves will be clear, to achieve what he wants, a fight with Butler has to take place and he has to win.

Could we see Butler challenged by Inoue in the near future? It certainly sounds like it with his aims clear. Butler has already hinted at the potential fight going ahead.

After Inoue's win, he had this to say: "I hope he does want to try and be undisputed. It'd be an absolute honour to step in the ring with a pound-for-pound great… Joe [Gallagher] will come up with a game plan. It'll be a tough task, but it's a task I'm willing to take."

After watching that footage of the knockout, Butler will surely be wary of taking on the Japanese boxer given his capabilities. If he can replicate that performance he’ll surely be a match for anyone in his division?!  

But that doesn't seem to phase the WBO belt holder, who looks set to take on the Japanese man sooner rather than later!

Even the commentators were worried about Inoue, stating ‘that man is scary’ after his brutal knockout over Donaire.

The footage of the knockout will certainly send shockwaves around the boxing world as Inoue looks to make a name for himself as one of the best pound for pound fighters in the world right now.

It’s three years after Inoue vs Donaire 1, with the Japanese star making it much more comfortable this time round.

First time out in 2019, Inoue had to rely on a unanimous decision rather than a knockout to secure the W, in a bout seen by many as the fight of the year.
