Marco Huck is confident that he has the skills to cause a major shock when he makes the step up to heavyweight to challenge WBA champion Alexander Povetkin on Saturday.
The German has just one defeat on his impressive record and has since defended his WBO cruiserweight title on eight occasions in the last three years, before moving up to heavyweight.
Huck firmly believes that he has the tools to upset the former Olympic champion, despite the fact that he will step into the ring around two stone lighter than his opponent.
"I'm ready to become heavyweight champion," said Huck. "I would not have taken the fight if I didn't believe in myself.
"Povetkin is good, but I can beat him. We once did sparring together and he has bad memories of me. On Saturday, I will be the new champ. He is going down."
However, Povetkin has dismissed the challenge of Huck and admits that he was surprised to hear that the fighter would be challenging him at heavyweight.
"At first I was surprised about Huck's challenge because he has never fought at heavyweight before," said Povetkin, who has won 16 of his 23 bouts by knockout. "But I am happy to defend my title against anybody out there. I am in great shape and I will win."
