Retired boxer Floyd Mayweather has agreed to become a “special advisor” to China’s Olympic team, according to the Chinese Federation.

It said the former five-weight world champion, 42, will support the team as they prepare for Tokyo 2020.

The announcement was made on the federation’s official account on Chinese social media platform WeChat.

Zou Shiming won China’s first Olympic medal at Athens 2004 and they won four medals at Rio 2016.

Mayweather retired from for a third time after beating UFC fighter Conor McGregor in 2017, giving the undefeated American a professional record of 50-0.

On December 31, 2018 Mayweather beat Japanese kickboxer Tenshin Nasukawa in an exhibition bout worth a reported $9m (£7.07m).
