Floyd Mayweather and Manny Pacquiao may be moving closer to agreeing terms for a long-awaited bout. The pair have long been considered two of the best fighters of their generation but have never met in the ring. However, that may be about to change after Pacquiao's agent Fred Sternburg hinted to BBC Sport that talks between them were progressing.

Sternburg denied that terms had already been agreed for a May showdown in Las Vegas, but added: 'There is still a long way to go. 'At least the movement has been in a positive direction.' Mayweather, unbeaten after 47 professional fights, and Pacquiao, an eight-division world champion, have tried and failed in the past to reach an agreement. But with them now 37 and 36 years old respectively there may not be too many chances left. Both men beat Ricky Hatton before the Mancunian retired.
