Floyd Mayweather is giving Anthony Joshua advice ahead of his high-stakes rematch against Oleksandr Usyk

• Mayweather appears to be advising the British heavyweight once again.

Floyd Mayweather is giving Anthony Joshua advice ahead of his high-stakes boxing rematch against Oleksandr Usyk later this year.

The former five-weight world champion Mayweather has a long-standing relationship with popular British heavyweight "AJ."

Joshua once visited the Mayweather Boxing Club in Las Vegas. Mayweather and Joshua were seen together promoting an event in London. The American also flew by private jet to watch Joshua fight in a pandemic-era bout in 2020.

Through his gym and his events company, Mayweather Promotions, the 44-year-old wields significant influence over the fight game and its combatants.

Joshua would be one of Mayweather's most valuable partners in boxing. However, it appears the relationship remains casual, as the pair linked up in Dubai during a trip to the United Arab Emirates.

Joshua posted gym footage that showed Mayweather in the background in an Instagram story.

"The best to do it and always helping the next generation," he said in a caption. "Big respect, champ."

It is not the first time Mayweather has had the ear of one of Europe's biggest sporting stars.

In one of his greatest successes, Joshua rose from the canvas to knock Wladimir Klitschko down and out in a 2017 heavyweight fight that reinvigorated the sport's glamour division.

Many lavished praise on Joshua and, while Mayweather credited the "dog" inside of him, he also said, to his face, that he should get to the Mayweather gym so he can sharpen his defensive skills and not get hit so frequently.

That "mother fucker has got some dog in him," said Mayweather.

He added: "We want to tighten that defense up until it's real, real sharp and real, real slick."

Three years later, Mayweather flew to London to watch Joshua knockout Kubrat Pulev.

Wearing a mask, as Britain was enduring a lockdown period to help thwart rising coronavirus cases in the country, Mayweather watching the event from ringside.

After Joshua had won, he walked toward Mayweather, and the pair enjoyed a private conversation.

The 32-year-old heavyweight fought just once in 2021, losing a decision to Ukrainian Oleksandr Usyk in one of the year's best fights.

The pair of former Olympic gold medal winners will clash once again in the coming months.

Joshua and Usyk's rematch could take place in March.
