Anthony Joshua has told Joseph Parker he must put in a super-human performance to beat him in March.
Joshua and Parker are set for a blockbuster heavyweight unification bout in Cardiff on March 31.
Joshua’s IBF and WBA titles will be on the line and the British-born Nigerian will be looking to take Parker’s WBO belt.
Both fighters are undefeated in their careers to date and one of their perfect records will come to an end at the Principality Stadium.
But Joshua, who beat Carlos Takam with a 10th-round stoppage in October, insists he is not set to suffer his first loss.
The 28-year-old said: “It will take more than any human to stop me on this journey.
“It’s good to be back. I took my time last time out, but I got the win which is the most important thing.
“Now it’s about making history. It’s an honour to be up here with another world champion.
“I don’t know how to take his camp in terms of what’s been said. I take it with a pinch of salt. It’s for another strap and I know he’ll be working hard.
“One thing that separates me is I mix intelligence with hard work. I’m making sure my mind is in the right place because it will be a mental challenge.
“[Parker has] done very well. I like to study but I’m more interested in how I am developing.
“What I learnt from the amateurs is that I watched everyone and watching when you’re not there is not the same. I haven’t studied him diligently, but I will study him in my training camp.
“The focus is to win. I don’t know what his strengths and weaknesses will be. They will change.”
