The 39 year-old was greeted by some jeers from the pro-Pacquiao crowd, although his mere presence at the arena led to further speculation of a rematch with the headlining act.
Pacquiao revealed he’d actually invited Mayweather to come watch him.
Mayweather had earlier told reporters he would ‘absolutely’ consider a comeback from retirement, leading to immediate assumptions ‘Money’ would go for the most lucrative fight out there opposite Pacquiao.
The pair generated the biggest earner of all time in May 2015 and there are many fans out there who want Mayweather and Pacquiao to fight again due to the nature of their first meeting.
Despite Pacquiao looking good in regaining the world title, a return with Mayweather still seems a long way off becoming a reality, though, mainly due to the queue of Top Rank stablemates waiting at the door.
Vasyl Lomachenko has been mentioned by Bob Arum as a possible for 2017, whilst Terence Crawford was also ringside and is keen to put his two super-lightweight belts on the line against the ‘Pacman’ next year.
May would be the most workable date should Mayweather finally admit he will fight again, which would give the American an opportunity to reach 50-0 and break Rocky Marciano’s record.
