Floyd Mayweather Jr claimed to have "accomplished everything" as he confirmed his retirement following a unanimous points victory over Andre Berto in Las Vegas.

The self-proclaimed TBE (The Best Ever) rounded off his career with a victory that pulls him level with legendary boxer Rocky Marciano on an undefeated record of 49-0.

Some have speculated that Mayweather will look to bring up a half century of wins before finally calling it a day, but the man himself stuck to his pre-fight stance that he would hang up his gloves after having his arm raised on Saturday.

"My career is over. It's official. I am done," he said. "I'm almost 40. I've broken all the records. I have nothing to prove in boxing.

"I was able to make good investments. I'm well off. Hopefully one day we'll find another Floyd Mayweather.

"I'm leaving the sport with all my faculties. I'm still smart. I've accomplished everything.

"There's nothing [left] to accomplish in the sport."
