Eric Molina was announced last week as Anthony Joshua's next opponent and has already begun his war of words with the British IBF heavyweight champion.
The Mexican American has delivered a stark warning to Joshua, as he promises to not let up against the Brit when the two meet next month in Manchester.
In typical pre-fight style, Molina vowed: "I can definitely say one thing, I will hit AJ harder than he's ever been hit. That's going to happen on December 10.
"I will hit him harder than he's ever been hit and if he dances, and I can get him hurt, I will not sit back like I sat back with Wilder."
The Texas-born fighter was referring to last year's bout with WBC champion Deontay Wilder, when Molina delivered some devastating blows in the third round before eventually being knocked out in the ninth.
With his only title defeat to date still clearly on his mind, the 'Drummer Boy' will now know not to let up if he gains the upper hand against Joshua. He added: "I'll have to attack, if I have him hurt. I'm going for the kill."
In his last fight outside the United States, Molina defeated former world champion Tomasz Adamek in April and will hope to repeat his success against Joshua next month.
Despite being well into his professional career, the 34-year-old is adamant he has improved since his last fight.
"This is going to be the toughest fight of his career and only because I'm that fighter that has gone better throughout my career, I've gone better every fight, up until my last fight, up until now. He'll fight the toughest Molina that anybody has ever seen," Molina continued.
Joshua will hope to continue his extraordinary unbeaten run, which will reach 18 wins from 18 providing he defeats Molina on December 10.
It will be the second time he defends his IBF heavyweight title, after knocking out Dominic Breazeale back in June.
