Floyd Mayweather Sr. is sure that his son will be fighting Manny Pacquiao in the near future, despite no schedule for 2015 being released.

"It's gonna happen. That fight's gonna happen. Trust me," Floyd Mayweather Sr. told fighthype.com. "That fight's definitely gonna happen. It's a fight for the world, man, right there. It's the biggest fight that has ever been in life, so like I said man, that fight's gonna happen."

Mayweather Sr. says he has not learned from his son what specific fight was in his plans. However, with Mayweather Jr. saying that he will retire after his next two fights, Sr. is certain a megafight with Pacquiao is on the docket.

"[I'll] tell you right now, he never told me the fight's gonna happen, but ... the fight's gonna happen," Mayweather Sr. told the website. "You mark my words and we'll see."

Mayweather Jr., who is 47-0 with 26 knockouts, currently holds the welterweight and junior middleweight titles. The 37-year-old fighter has not made any specific announcements on his opponents other than that he expects to fight someone in May.

"I'm gonna go and talk to my team and see what the future holds," Mayweather said last month after his second victory over Marcos Maidana. "I don't know who I'm fighting in May but I expect to fight in May. Manny Pacquiao needs to focus on the guy in front of him. Once he gets past him, he can look to the future. If the Pacquiao fight presents itself, let's make it happen."

The 35-year-old Pacquiao will defend his welterweight title against Chris Algieri in China on Nov. 22. Pacquiao has said that a fight against Mayweather "could happen" in 2015.

The two boxing stars have taken some verbal jabs at each other through social media in recent weeks with Pacquiao saying "he acts like an uneducated person" and that "he should fear God." The insults and bad blood have only fueled excitement for a potential showdown between these two popular fighters.

Former champion Sugar Ray Leonard weighed in on the potential bout:

"They should fight ... That fight would be huge," Leonard told Fox 11 Los Angeles last month, according to ESPN. "I think fans are starving for excitement. Fans are starving for competition, evenly matched fights. But it would be huge."
