Poland’s undefeated heavyweight boxer Mariusz “The Viking” Wach will take on current WBA, IBF, WBO, IBO and The Ring heavyweight champion of the world Wladimir Klitschko (who spells his first name with a W, even in English), in Hamburg on November 10, it was announced last week.

The 32-year-old Pole, who has a record of 27 wins (including 15 KOs) and 0 losses, will face the toughest night of his professional career when he comes up against the man known as Dr Steelhammer.

However Mr Wach’s size, standing as he does at 6 feet 7.5 inches (2.02 meters), compared to Mr Klitschko’s 6 feet and 6 inches, means he is a genuine heavyweight whose height could trouble the champion.

“My fellow countrymen Adamek and Sosnowski did not have what it takes to beat a Klitschko [brother]. I am not a former cruiserweight but a real heavyweight. Klitschko will take a lot of hard punches before I knock him out,” Mr Wach said.

“I will be the first Polish world heavyweight champion,” the challenger added.

For Mr Klitschko, who has a record of 58 wins and 3 losses, including two victories in 2012 against France’s Jean-Marc Mormeck and American Tony Thompson, the fight could prove to be a genuine test.

“The big challenge for me is Wach’s height. It is the first time that I am facing an opponent who is taller than me and has a better reach. He is unbeaten, a big puncher and has an irrepressible will,” Mr Klitschko said.

His elder brother Vitali Klitschko will defend his WBC heavyweight title against Manuel Charr in Moscow, on September 8.
