WATCH: New Mayweather interview reveals tragic upbringing and how he outsmarted Pacquiao

If there's only one Floyd Mayweather interview to watch between now and his retirement, this is it.

Just four days on from Mayweather's unanimous decision victory over perennial rival Manny Pacquiao, Money has detailed the stress that he has exorcised with the most important win of his life. In a tremendously in-depth interview with FightHype, the undefeated welterweight revealed the toughness of his upbringing.

"My mother's brother shot my dad while my dad was holding me, when I was a little kid... My mother was on drugs and my dad went to prison for dealing drugs, and he wasn't small time."

The pound-for-pound greatest in the world right now also reveals how he would admirably bring any winnings he'd make when he first started boxing internationally back to his mother, who he calls his "sweetheart." And in relation to the biggest fight of his life, it's hard to argue with Mayweather's opinion on the naysayers who believe that his victory over Pacquiao on Saturday was a boring display.

"If I would have had fought Manny stupid and reckless. And say, hypothetically, that something would have happened. You know what the fans would have written today and what the writers would have written today? 'Floyd fought dumb. Why didn't he stick to his gameplan?'"

Mayweather doesn't underestimate the importance of his victory over Pacquiao, who many were considering his biggest test to date, as he revealed the significance of the win.

"Today is a good day not because of my victory but because I took a lot of stress off of my father. I took a lot of stress off of my mother. I took a lot of stress off of the people on my team. I took a lot of stress off the people under Mayweather Promotions."

He was also quick to hit back at critics who are irritated by the amount of time that it took for Mayweather v Pacquiao to finally happen, with many believing that the fight happened when both were past their prime.

"The thing is that if he took the blood and urine tests, a long time ago we could have did it."
