Boxing is one of the world's most competitive sports, and being a combat sport it can create some of the fiercest rivalries in the sporting world.
Rivalries such as Chris Eubank and Nigel Benn, Sugar Ray Robinson and Jake LaMotta, and the 'Thriller in Manila' Muhammad Ali vs Joe Frazier.
The intensity of the rivalries between the fighters can manifest outside of the ring in explosive press conferences and weigh-ins, and can even last after they've retired from the ring, but most of the time it's friendly banter with former rivals.
Another well known rivalry was between Carl Froch and recently retired former super-middleweight champ George Groves.
The British boxers fought each other on two occasions, the first was November 2013 where Froch controversially won by TKO in the 9th round.
They both exchanged insults before and after the fight, and went on to have a rematch six months later at Wembley Stadium for Groves to have a chance at revenge over his rival.
Froch went on to beat Groves by KO for a second time and the beef between them was considered to be put to bed That was until recently when Groves announced his retirement from boxing.
Groves lost the WBA super-middleweight title to Callum Smith in September and has since announced his retirement from the sport at the age of 30, with a record of 28 wins and 4 losses.
His former rival Carl Froch has since weighed in on the announcement and said he thinks Groves went past his best back in 2014 when he lost to Froch for a second time, Groves, however has shrugged off the comments,
"It's Carl, so he shoots from the hip, and he's fully entitled to do that whenever he comments about myself, because we had a real intense rivalry," Groves told Sky Sports.
"As much as I wish it was different, he came out on top, so fair play to him."
Groves then went on to comment on his other rivalry with James DeGale and winning the world title at his fourth attempt against Fedor Chudinov.
"My greatest, sweetest moment was winning that world title at the fourth attempt, which was do or die at that point, and I didn't know if it was actually going to happen," he said.
"But of course, always getting a win over my fiercest rival James DeGale is just as sweet."
Groves has now said he is aiming towards some form of management after hanging up his gloves, as he wishes to remain part of the boxing world,
"Retiring at 30, pipe and slippers, and a round of golf don't quite fit the bill for me," he continued.
"I would rather retire from boxing with a new goal in mind, and we've got a few things I would love to get stuck into now, whether that be working as a manager maybe. Aiming to stick in the sport."
As Froch is now a regular boxing pundit and commentator for Sky Sports, perhaps we will continue to see the two former rivals clash, outside of the ring.News Now - Sport News
