And viewers just can’t get enough of it.

The crowd at the O2 Arena in London were awestruck as the one-punch knockout seemed to take even Diakiese himself by surprise.

Footage of the Doncaster native’s sensational first round knockout victory over Packalen has been shared thousands of times after the UFC London event on Saturday night (March 18).

In it, the 24-year-old makes light work of his Finnish opponent, sending him flying to the canvas with a vicious overhand right in a little under 30 seconds.

It was essentially Diakiese's first punch of the evening, and he stiffened Packalen's body with ease.

“I’ve been saying it all week and I’ll say it again,” Diakiese said after his win.

“That was easy work. I’m one of the best and I will keep proving it.

“I’m interested in fighting on the Sweden card in May and then put me on the Glasgow card in July. Whoever is next, I will be ready.”
