Anthony Joshua Jarrell Miller

Jarrell Miller, the New York challenger for his world heavyweight titles come June 1, accused Anthony Joshua of using steroids to build his knock-out physique and claimed that Wladimir Klitschko had been worried about the same issue before that Wembley Stadium mega-fight.

Joshua hit back with a reasoned rebuttal, outlining his physical development from golden Olympian to professional champion and adding: ‘I never stick needles up my a*** and I get tested all the time.’

They made their cases in separate hotel meeting rooms after vacating the podium where they posed peacefully for chest-to-chest photos and exchanged mildly laughable threats, Joshua warning: ‘I will be the surgeon who reconstructs your face.

‘This is all I do. I know how to knock people out and beat them up. I’m going to strip him of his soul in that ring.

‘I do the job, I am a good boxer, heavy-handed puncher and have beaten better opponents than anyone else out there.’

Once they were apart, Brooklyn’s Big Baby kicked off: ‘Nobody could have put on 20lb between winning the Olympics and his first pro fight the way Joshua did without taking something. Impossible.

‘We’ve busted our balls to get full testing for 10 weeks to make sure he’s clean before June 1. We’ve covered the bases. If he’s been taking performance-enhancing drugs I couldn’t care less now. I’ve studied him. His physique, his power, his stamina.

‘Since he won his titles his body’s slimmed down and he’s only really knocked out opponents who backed away. There’s not the same strength and stamina.

‘Klitschko pushed for testing. In what subjects did Wladimir and Vitali get their PHDs? Sports medicine. Why did people who know everything about physics of the body want Joshua to test every other week? They pushed on that but settled a bit to make the fight.’

Joshua responded icily: ‘I take that as a compliment to all my dedication and strength and power training. If I was on steroids as well I wouldn’t fit in this shirt (a slim-tailored grey number, as it happened).

‘He’s talking bull. At the London Olympics I was around 104 kilos and then weighed 107 kilos for my first pro fight the next year. What’s that, just half a stone with pro training? And he’s only talking about one year.

‘What about the 11 years I’ve been boxing since I was 18. I’m now 115 kilos so that’s averaging just one kilo more a year. And that’s down to how hard I work and live. To all the strength and stamina training and weight-lifting. To how I control everything I eat and how I dedicate myself to boxing. It’s my life. It’s pretty much all I do. And it’s expensive, the food and the drink and the lifestyle.

‘I’m actually cutting weight now so it would be pretty odd if I was doing anything. By the way, all the anti-drugs programmes I’m signed up to cost plenty, too. I have to let them know where I’m going to be every day. I get random tested roughly twice a week round the year by VADA (Voluntary Anti-Doping Association) at a cost of £40,000 a test. And nothing. If ever there was something wrong in my next 10 years boxing it would be an accident. I don’t do anything.’
