H2H it would be a massacre. Ali would eat him for breakfast. Wlad is way to static. I don't want to sound like a hater but Ali is positively the worst matchup I can think of. I'd give Wlad more chance against Tyson tbh.
I would happily cheap someone with a bottle to the back of their head if I saw them in a bar claiming Ali would beat Wlad. The ignorant ****.
