George Jarvis fighting Rungrawee Sitsonpeenong for revenge rematch with ONE Championship world titlist Regian Eersel

Britain's George Jarvis is gunning for a revenge rematch with world champion Regian Eersel.

ONE Championship Muay Thai world titlist Eersel stopped Jarvis last year. But the British star regrouped and delivered a stunning win against elite fighter Sinsamut Klinmee in March.

Now if he can defeat Rungrawee Sitsonpeenong, live on Sky Sports in the early hours of Saturday morning, Jarvis is adamant he will put himself in the frame for another shot at Eersel.

"That's the plan. Regian Eersel, the champion, he's just gone five rounds with Rungrawee. Rungrawee himself has shown his level. If I go out there on Saturday and knock him out then there's no questions asked," Jarvis told Sky Sports.

He's convinced he is now a radically improved fighter.

"There's nothing but respect for Eersel, he's a great champion and he's done amazing things within the sport. But there were a lot of mistakes I made that camp and that day. Unfortunately I paid a price. I'm a very firm believer in mistakes don't happen twice. Next time we run it back it will be a completely different story," he said.

"I'm a different person now. It was almost like a wake up call. My training's different, my mindset. I feel like I've evolved a lot. I've matured a lot. I think my fighting's got better and better and I'm happy and excited to show this for Saturday.

"I turned it up, I took Sinsamut out," he added. "I want to keep knocking these people down until I get my shot again."

Jarvis has previously beaten Rungrawee, in what was a key moment for his career. After that knockout win, live in the post-fight interview he negotiated a ONE Championship contract for himself.

"Saturday, it's strictly business. And I hope he forgives me after!" Jarvis said.

But he warned: "I know how hungry he's going to be.

"Just because I knocked him out last time doesn't mean I'm going to knock him out this time. It's never as simple as that.

"I've been the hammer and I've been the nail. We're expecting Rungrawee to come out for a very good fight and we're more than ready."
