Jack, 33, fought back from a devastating knockout loss to Derek Edwards in 2014 to eventually pick up the coveted green and gold belt and Mayweather beamed with delight when speaking about the US-based Swede recently.
“I’m very proud of Badou Jack. He’s a guy who carries himself like a gentleman. That’s what a true champion does. He’s very respectful, humble and appreciative,” said Mayweather.
“Badou Jack is such a hard worker and he’s very appreciative. I remember the position he was in. He’s still very thankful and humble now that he’s in a great position in his life and career.
“I’m just happy that I’m able to put fighters in a good position. They then have to take advantage of the position I put them in.”
On staging the Jack v DeGale event at the Barclays Center in New York City, Mayweather added:
“What better city to be in than New York City? It was always one of my dreams to fight in New York City.
“I’m glad I’m in a position to put fighters out there to give the fans what they want to see. New York City is the best place for boxing.
“We want to bring boxing to New York City. This is one of the meccas of boxing. The whole state has embraced me throughout my career,” he added.
