With victory, Mayweather's record surpassed that of the great Rocky Marciano by improving to 50-0.

He has earned so much money that, particularly with the minimum £78million he is reportedly guaranteed from defeating McGregor, he should never need to fight again.

McGregor's minimum reported purse of £23million also represents his biggest day, but even despite this one-sided defeat his popularity within UFC means he can swiftly fight within it again.
