Wladimir Klitschko will take on Francesco Pianeta in May to defend his WBA, IBF and WBO heavyweight titles.
The fight will be held in Mannheim on May 4 and will see Klitschko clashing with his former sparring partner.
However, Pianeta says that he is confident that he will win the fight.
"Many see me as an outsider but I will knock Klitschko out and turn the world of boxing on its head," BBC Sport quotes him as saying.
Pianeta is unbeaten in 29 professional fights, having won 28 of them and drawn just once.
