The British boxer has been trying to secure a bout with the Ukrainian fighter, who currently holds the WBA, IBF, WBO and IBO world heavyweight champion belts.
"Tyson Fury? No. I don't have a particularly high opinion of Tyson Fury. He's a big and strong guy, but he can't throw a punch. He slaps rather than hits.
"Wladimir Klitschko would knock Tyson Fury out. Fury against Vitali? Look, I'm not impressed with Tyson Fury. He's a big guy, throws a lot of punches, but Vitali would beat him."
Fury, who is unbeaten during his professional career, last fought against American Kevin Johnson in December.
