Anthony Joshua and Dillian Whyte went to war in an attempt to settle their rivalry back in 2015.
The pair were unbeaten, inexperienced heavyweight prospects at the time with Joshua’s record at 14-0 and Whyte’s at 16-0.
As amateurs back in 2009, AJ was handed his first defeat by Whyte, who dropped him and beat him on points in a three-round contest.
Joshua had since gone on to win Olympic gold at London 2012, becoming one of the nation’s golden boys.
Meanwhile Whyte turned pro with significantly less fanfare.
Bad blood developed between the north and south London rivals, with Whyte doing his fair share of trash talking in the build-up.
Fans saw a different side to Joshua also, as the fight quickly became about more than just the British title belt at stake.
Finchley’s AJ recruited Stormzy to diss Brixton’s Whyte as he rapped during the ring walk and the tension was palpable at the O2 Arena when the first bell rang.
Up to this point, nobody had taken Joshua further than three rounds and he started the fight seeking another early finish.
After sitting back and listening to his opponent’s insults throughout the build-up, now was his time to exact revenge.
The gold medallist fought like a street thug, hurling combinations of hooks and uppercuts which hurt Whyte on multiple occasions in the opener.
AJ even stuck his tongue out and shouted, ‘What?’ at his opponent as he teed off on his head.
However, much to the frustration of the bookies’ favourite, the gutsy underdog stayed standing.
As the bell sounded to signal the end of a torrid opening round for Whyte, Joshua attempted to add further punishment and hit him with a late left hook.
Then, all hell broke loose.
Referee Howard Foster jumped in between the pair and separated them, but Whyte hurled a left of his own in response.
He then stormed across the ring and threw a huge, looping right hand at AJ which missed by a whisker.
Whyte explained to iFL TV after the fight: “I’m not gonna let no-one beat down on me.
“He hit me after the bell, so I retaliated. I ain’t no punk.”
This prompted a brawl as entourages from both corners stormed the ring to try and break up the action.
Whyte’s trainer Johnathon Banks restrained him in one corner while Joshua’s coaches got him back to his stool.
Meanwhile, approximately 25 other members of Team Joshua and Team Whyte were confronting one another in the middle of the squared circle.
“I was getting dragged to my corner, going, ‘Sit down,’” Joshua recalled.
“That’s what the fight game is. The difference of that fight was there was more than just the British title on the line.
“It was more about bragging rights and that’s what was on the line.
“That’s why the fight kicked off because that don’t really happen in a good sportsmanship fight, it happens when there’s pride on the line.”
Thankfully, the team confrontations did not turn too violent and security quickly regained control.
Joshua added: “Did I think he could be disqualified? Nah. It’s fighting, innit? It’s not like this is golf, this is fighting.
“This is what you’ve gotta expect, you’ve got real bad blood on the line, that happens in the ring.
“Security done a great job. Calm it down, get us back to our corners and continue the fight.”
At the start of round two, referee Howard Foster brought both men to the centre of the ring and gave them serious warnings.
He then allowed the contest to continue, much to the relief of the all those who’d paid for tickets or pay-per-view.
A brilliant battle ensued between the two Brits as Whyte fired back and wobbled Joshua in the second.
He failed to capitalise though and AJ regained control before eventually finding the finish with a brutal seventh-round KO.
