Floyd Mayweather and Manny Pacquiao will step into the ring Saturday night in Las Vegas at the MGM Grand Garden Arena for one of the most anticipated fights in the history of boxing.

Many people thought this fight would never happen, but neither boxer could claim to be the best of this generation without fighting each other at least once.

There’s no question that more pressure is on Mayweather, who’s putting his perfect 47-0-0 record on the line against the most dangerous opponent of his career.

Money May is a defensive fighter who unleashes devastating combos on the counter attack when his opponent makes a mistake. If Pacquiao can be aggressive and attack Mayweather early without leaving himself too vulnerable, he will have a chance to win in the later rounds.

The welterweight championship of the world is at stake. Which fighter will cement his legacy on the sport’s grandest stage?
