The 32 year-old New Jersey-based fighter, who is unbeaten in 27 contests, stand 6ft 7ins tall and believes he has all the attributes to cause 'Dr. Steelhammer' problems he hasn't had to deal with from his most recent challengers.
"I'd like to thank Wladimir, his manager Bernd Boente and the entire Klitschko team for giving me this opportunity," said Wach.
"I can't wait to prove to the world what I'm worth. I will prove the critics wrong. Klitschko hasn't faced an opponent like myself in over several years.
"Poland deserves a true heavyweight champion. My friend Tomasz Adamek had a shot but because he was smaller and had shorter reach he didn't really have a chance. This time you will witness the real super heavyweight fight."
