Ammon News - ANTHONY JOSHUA warned Tyson Fury boxing is 'for the uncivilised' and 'a sport of combat and war'.
It comes with the heavyweight champions still negotiating a potential two-fight deal for this year.
AJ sent out the war cry on his YouTube channel, where he broke down his last win, a ninth round knockout against Kubrat Pulev.
Joshua said: "Some people may not understand it and I realise in this life is that, 99 per cent of the population are civilised people.
"The job I've chosen is for the uncivilised. This is a sport of combat and war.
"We're not civilised people, we're warriors, and I love it."
Joshua returned to the ring in December, 12 months after he avenged defeat to Andy Ruiz Jr in a rematch.
Against Ruiz, 31, and Pulev, 39, AJ showed off a reformed boxing style, with added patience.
But Joshua insisted whoever the opponent or challenge, he is able to adapt and conquer.
He said: "No matter what the tactics are, no matter how much you study, no matter how much you think you can beat me, I'm just there to win.
"I'm there to do a job, and that's the fighter's mentality."
Joshua, 31, and Fury, 32, are set to put their WBC, WBA, IBF and WBO belts on the line as well as heavyweight bragging rights in June.
Promoter Eddie Hearn revealed the only hurdle left to overcome is contracts officially being exchanged before they decide on a fight venue.
Hearn told iFL TV: “I hope that we can finalise contracts in the next two weeks.
“And then the plan from there is to go out and start discussing with the various sites that have approached to stage this fight.
“What we wanna do is make sure we’ve got a deal papered to move forwards and start having these conversations, and then lock in the venue and the date.
“There isn’t a lot to be sorted. We’re in a good place. I believe we’ll have these contracts finalised in the next couple of weeks.
“I believe this fight will take place in June.”
