Londoner George Groves is ready to burst onto the world scene as he challenges for the WBC world title in Las Vegas on Saturday night.

The 27-year-old takes on super-middleweight champion Badou Jack this Saturday night, live on BoxNation, on the undercard of pound-for-pound king Floyd Mayweather's last fight against Haitian hard-hitter Andre Berto.

It's been a whirlwind career for Groves who has twice fought for the world title, those being two defeats to rival Carl Froch, but having bounced back with two wins - including capturing the European title - he insists he is now ready to take the boxing world by storm.

"Every fight is more vital than the last, more important than the last and there's more to lose, especially once you've lost," said Groves.

"I came back after losing last year and won the European title and I became the mandatory challenger of the WBC. Since then we've been rolling and waiting for our opportunity to fight for the WBC belt. We knew it would come so we've been patient with it.

"People will consider this a 50-50 match up. We're going to go in there and show people that they couldn't be further from the truth. We're in a great place and we're just ready to perform, to steal the show and arrive on the world scene.

"So all the pressures and all the excitement and everything else that goes with fighting for the world championship, I don't feel any of it because to me, it's just a fight."

Hammersmith hero Groves has spent the last two months training in the US at Big Bear Lake, undergoing gruelling mountain runs to whip him into shape.

Up against Jack he'll face an opponent with a record of 19 wins, with just one loss and a draw on his record, but Groves insists the Swedish-born fighter won't be on his level.

"We have plenty of motivation up here in the mountains. We're working hard. It's been a lifelong dream to become world champion. We're just concentrating on Badou Jack," Groves said.

"This is a fight against a good guy, but a guy who is not as good as me. For that reason, we're just looking forward to getting in there and performing. And winning and everything that goes with it.

"Without trying to give too much away about the game plan, we know Jack's strengths. We know his weaknesses. We plan to go in there, nullify his strengths and expose the weaknesses.

"But we're in phenomenal shape. First we came up here, I was in good shape. I was struggling to breath because of the altitude. But now, we are flying. We're getting better results than we do back in London when we're out in flat land and there's more oxygen.

"We're going to go bring the fight to Badou Jack and make sure he works for every second of every round. From there on in, the game plan will develop."
