Muhammad Ali vs. Tyson Fury would be the GREATEST FIGHT OF ALL TIME ... period, so says The Greatest's grandson, professional boxer Nico Ali Walsh.
TMZ Sports talked to the 21-year-old, 1-0 boxer ringside following the Fury-Deontay Wilder trilogy fight ... and we asked him how Fury would've fared against his legendary grandfather.
"That would be my favorite fight to watch. That would be the greatest fight of all time. The press conferences would sell out, the weigh-ins would sell out. The fight would sell itself," Ali-Walsh said.
