Manny Pacquiao is still one of the world's elite boxers at the age of 41.

Pac-Man is the first fighter ever to hold world titles in four separate decades after he took his WBA super-welterweight title into the New Year.

The Philippine fighter is showing no signs of slowing down for 2020 either, following his victory over Keith Thurman back in August.

That's because his plans for his return to the four-cornered ring this year would send shockwaves through the sport - and probably not for the right reasons.

Sean Gibbs - Pacquiao's promotional partner - told The Sun in an interview that Pac-Man is planning to fight both Floyd Mayweather and Conor McGregor in 2020.

"The Senator is looking to return in April of this year," Gibbs said. "Possible opponents that are out there are Danny Garcia, Errol Spence, Shawn Porter.

“As per a fight with the Senator and Conor McGregor - Conor has mentioned it a few times and if there was interest from the fans the Senator would consider the fight.

“Floyd Mayweather put it out himself in an interview that he is coming back in 2020 and one of the fights will be the Senator.”

The rematch against Mayweather almost seems a given with The Money Man set to come out of retirement this year.

He's also teased crossover fights with McGregor and Khabib Nurmagomedov on his official Instagram following the former's victory over Donald Cerrone on Saturday evening.

There would naturally be interest in both fights, as there would be if McGregor moved back into boxing to take on Pacquiao.

But is it good for either boxing or UFC? While it would generate revenue and bring sets of fans together, there is the risk of devaluing the competitive nature of both sports.

After all, the fighter making the crossover is almost certain to lose on every occasion, so what is the overall endgame here?

Sadly, only the making of money. If Pacquiao respects the sport, he'll take on the big guns in his weight division instead.
