And what if you can compare the different eras of boxing? Who would win the fight between Muhammed Ali and Mike Tyson - both in their prime? Would Vitali Klitschko stand a chance against the great Rocky Marciano?
Many attempts have been made to determine the all time greatest champion - both by analysts and experts, but ListWoo gives you the chance to offer your opinion. Who is the best heavyweight fighter the world has ever seen?
