George Groves will not "lose any sleep" over a rematch with James DeGale if he dethrones WBA and IBF super-middleweight world champion Carl Froch at Wembley Stadium.
DeGale will fight on the Froch-Groves undercard on May 31 after joining Groves' Matchroom Boxing stable.
Challenger Groves pledged to respect the mandatory fight calls should he claim Froch's titles at the end of the month.
The 26-year-old Londoner admitted he would be happy to face a rematch against DeGale, after beating him on points to the British super-middleweight title in 2011.
"I won't think past this fight because you can never tell what's going to come after this," Groves told Press Association Sport.
"This is being billed as the biggest fight in British boxing history, and once I beat Carl I might have a mandatory and that might be James DeGale.
"It's not a fight I'm going to lose any sleep over, though, because I'd beat James DeGale seven nights of the week.
"Again, it will be excitement about the new challenge, and as a new world champion people would be coming looking for me.
"You don't have to force your way into positions - I'd be world champion and it would come to me.
"So I don't need to think about things like that, because in that situation every door will open for me.
"And we'll take whatever the most exciting fight is.
"For now it's all about concentrating on dethroning Carl Froch.
"You end up at the top of the tree, if you're world champion, but commercially I'd be one of the biggest names in British boxing.
"So big news would be coming my way, my profile will go up and there will be opportunities against bigger international names."
Confident he will be in his best-ever shape for the eagerly anticipated rematch with Froch, 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."
