The Brawl in Montreal: Sugar Ray Leonard vs Roberto Duran
The first fight between the two legends is regarded as one of the greatest fights of all-time in the Canadian city.
To celebrate their greatness, Planet Sport has decided to review every single fight from 1980 to 1989, beginning with the Brawl in Montreal.

The event was promoted by American Hall of Famer Bob Arum. Neither man had the best of preparations going into the fight.
Leonard - who received a $9million purse for the contest - was sick with a virus while Duran got forced to undergo a two hour examination by a cardiologist because of his irregular heartbeat.
An Olympic champion, nicknamed "Sugar" - the same alias as Ray Robinson - with a gleaming smile and resounding presence of superstardom, Leonard was the posterboy of boxing.
The eventual result of an exhausting-yet-exhilarating night of action saw "Hands of Stone" inflict the first defeat of Leonard's career via unanimous decision - a result which originally announced a majority decision to the South American.
Mind games the key
"But Duran, he just had a way of getting under his opponent's skin. He'd do things that really pissed off guys. Ask Ray, he'll tell you."
"He had got into my head. It bothered me as a man. You don't insult a guy's wife," Leonard said.
"We give each other hugs now instead of punches and I'm proud to call him a friend."
