Top rated super middleweight contender George Groves is promising to do a real job Martin Murray this coming Saturday night.

The two fighters will trade punches in a WBA final eliminator as part of the Sky Sports Pay-Per-View undercard to Anthony Joshua's first defence of his IBF heavyweight title against Dominic Breazeale at The O2 Arena in London.

Groves has been rebuilding his career since last September's twelve round split decision loss to WBC champion Badou Jack. He feels ready to go and says his trainer Shane McGuigan put together the perfect game plan for the contest.

Groves admits his career is on the line in this upcoming fight. A loss could very well spell the end for him as a top fighter. If he loses, Groves has gone on record that he doesn't have any interest in rebuilding again.

"I've always been vicious mentally but, physically, I've struggled to get it off as good as I can do but this year I feel like a new man and Martin Murray is in a world of problems, he's in big trouble. I've never felt so big, so strong, I don't think I've ever hit so hard, never felt so sharp," he told Sky Sports News HQ.

"It's all for this moment because this is the pinnacle fight for me. There are a lot of big plans on the horizon, certainly I can't afford to have a slip up on Saturday night and I don't envisage doing that.

"I'm going to win and win well, and show everyone in the world that I'm a force to be reckoned with at super-middleweight. The hunger never left me. I feel like I'm really focused just on my business now, working with Shane McGuigan and his team, they relieve a lot of stress and pressure that comes with pro boxing.

"I've had it easy in that we have the football to distract us a little bit but the boxing comes in this weekend and I think everyone is excited about it. It is just kicking off the week of the excitement, let the circus start unfolding. We have got press conferences this week, obviously the weigh-in and then the fight on fight night so I'm looking forward to it."
