Producing one of the best fights of all time, this heated rivalry between two all-time greats will forever be the benchmark.
- Arturo Gatti vs Micky Ward
Not really a rivalry as these two became the best of friends, but their three meetings were 30 of the best rounds of action in history.
- Marco Antonio Barrera vs Erik Morales
Another trilogy, though this one was fought over three different weights, and cemented the status of these two Mexican warriors.
- Sugar Ray Leonard vs Roberto Duran
Two of the Four Kings fought each other three times over the course of nine years, though it was their first two back-to-back contests in 1980 which made this rivalry special.
- Riddick Bowe vs Evander Holyfield
Fights one and three of this vicious trilogy were sickeningly brutal, while the second included the infamous ‘Fan Man’ incident.
- Chris Eubank vs Nigel Benn
There was genuine disdain between these two do-or-die fan favourites. Their first fight was brutal, while their second clash ended in a draw.
- Tony Zale vs Rocky Graziano
From 1946-1948, these two fought three times, all ending early and all serving as timeless classics.
- Sugar Ray Leonard vs Thomas Hearns
Their first fight was one of the most anticipated in history, Leonard producing a 14th-round stoppage, before they fought to a draw eight years later.
- Manny Pacquiao vs Juan Manuel Marquez
Blood, guts and one of the most brutal one-punch knockouts ever; this four-fight rivalry had it all.
- Carl Froch vs George Groves
A historic (whisper it) 80,000 flocked to Wembley Stadium to see how this bitter rivalry would conclude.
