To mark Rivalry Weekend on Sky Sports, we pick out five of British boxing's fiercest rivalries. One duo will fight again soon, another crosses generations and in all of them, their names are usually mentioned in the same sentence...
They grew up a few miles apart in west London, they boxed in the same amateur club, Dale Youth, and sparred hundreds of rounds, but have never been friends.
Points wins in the amateurs and an intense grudge match at The O2 in 2011, all went Groves' way. Yet DeGale went to the 2008 Olympics and became the first British boxer to strike gold, and then be crowned a world champion.
For seven months last year, they were super-middleweight world title holders and tables might have turned of late, but Groves and DeGale are still asked about each other. This rivalry runs deeper than most.
Two of Britain's biggest names have been at war for years - and still are. They sparred before they met on that infamous Ringside show six years ago, and the call-outs have rarely stopped.
They both hit the welterweight division then Khan went for Saul 'Canelo' Alvarez and Brook for Gennady 'GGG' Golovkin but the losses seemed to bring them even closer.
Khan has since joined Matchroom, so surely Eddie Hearn can finally put them together. The weight issue seems to be the only obvious hurdle left...
They never fought each other at cruiserweight but as soon as he won his world title, Bellew went for the biggest name he could get his hands on... Haye.
The heavyweight rivalry started socially, but as soon as the first fight was confirmed, it suddenly became nasty. Punches were thrown at the press conference, the public lapped up their animosity.
Forget the cuddle after the first fight, the respect has gone for the rematch. Haye knows he needs to win, Bellew is looking forward to proving him wrong again. And the pleasantries will be put on hold.
These two are never going to be top of anyone's Christmas card list, especially each other's. A heavyweight battle between north (Chisora) and south (Whyte) London, was a December duel that turned nasty, before a punch was landed.
Remember the Gloves Are Off show had to be curtailed, when security had to separate them after a glass was thrown. And then what about Chisora hurling a table at his foe at the press conference?
The fight was another matter, both throwing everything into it, Whyte edging the decision. Chisora felt he was hard done by and still wants the chance to reverse the decision.
If you thought this rivarly was done and dusted, think again, because Frampton has reignited the fire that burned between them two years ago.
The pair met in a super-featheweight unification fight and after losing, Quigg immediately set his sights on redressing the balance.
Both changed trainers, both moved up to featheweight, Frampton being the first to win a world title at 126lbs. Now, if Quigg can do the same this weekend, 'The Jackal' is happy to meet him again.
