Super middleweight George Groves is confident he will be in his best-ever shape for the eagerly anticipated rematch with IBF/WBA 'regular' champion Carl Froch, and Groves said his biggest challenge now is to stay calm until the bout.

Froch saw off Groves in November 2013, only for the IBF to order a mandatory rematch after controversy over referee Howard Foster's handling of the fight.

Groves said he will accept no distractions as he gears up for the Wembley showdown.

"You never really get a mental break, but you don't want a mental break because that affects everything else," the Hammersmith-born fighter said.

"It's just containing the excitement really, working hard and making sure that pays off.

"There are a few differences this time because you want to improve every time, and keep pushing boundaries.

"We surpassed the fitness test levels set for the first fight with Froch with five weeks to go to this fight.

"It's been a nice long camp for this, training hard and working on everything from technique to fitness and conditioning.

"I feel fresh, though. I feel like I've only just started. I'm feeling the benefits and that's exciting.

"I'll definitely be in the shape of my life - I feel great.

"It feels effortless - there's no struggle, no strain. It's just calm, composed, relaxed.

"And that's not just sparring - (it's) across all aspects of training and all aspects of camp.

"I've got the fight that I wanted and now I just can't wait to get out there and put in a performance."
