Huck will defend his WBO cruiserweight belt in a rematch against veteran compatriot Firat Arslan on Saturday in Stuttgart.

Huck has already challenged for a heavyweight title when he lost on points to Russia's Alexander Povetkin for the WBA belt in February 2012.

But he has already promised his respected German trainer Uli Wegner he will one day be a heavyweight champion.

"I told my coach this week that one day that I will be his first world heavyweight champion," Huck boasted to German daily Die Welt.

"If I were to have the chance tomorrow, I would guarantee it."

The 29-year-old is relishing his rematch against Arslan, the 43-year-old who took Huck to 12 rounds in November 2011 before losing on points.

Wegner has said he expects Huck to be a world heavyweight champion "by January 1 2015" and a possible contender for the WBC belt, vacated after champion Vitali Klitschko's decided to move into politics.

Huck's heavyweight ambitions would put him on a direct collision course with Klitschko's younger brother Wladimir, who holds the WBO, WBA, IBF and IBO belts and has vowed to keep the WBC title in the family.

But for the time being, Huck is more interested in seeing off his challenger Arslan in Stuttgart.

"Firat has the condition of ten horses, but he can't really box," quipped Huck.
