I think Manny Pacquiao is already needed to retired. He will not win this time because he is now old the body becomes weak, he is no longer faster as before.
How sure are you mate?
Senator Manny Pacquiao is still strong until now with the boxing ring he can still fight.
One thing that comes to my mind why he is continued fighting in the ring even he has many holding belts.
All of these just for his political career that wins or lost people of their country will still love him and re-elect for senator when elections come to their place.
