Watch Floyd Mayweather destroy sparring partners in build up to Andre Berto fight

With a meeting with Andre Berto on the horizon, there isn't the usual hype that surrounds a Floyd Mayweather fight.

In recent weeks, it seems  his ongoing war of words with Ronda Rousey has generated more headlines than his September 12 bout with Berto. As a reminder of the upcoming Vegas fight, footage of Mayweather landing blows his sparring partners at a media day has been released. With 'Money' producing a defensive masterclass to earn victory against Manny Pacquiao, seeing him on the front foot in this footage is a rarity. https://youtu.be/DVieMMlqTMk
