Mayweather vs Pacquiao: The Pac-Man could be approaching his farewell fight, says Jim Watt

Manny Pacquiao could be nearing the end of his career, but that will mean he is more motivated than ever to defeat Floyd Mayweather, says Jim Watt....

I don’t think Manny can change. When Freddie Roach got hold of him he was like a left-hand happy, crude southpaw. But about five years ago, Freddie had him as the perfect fighting machine, he was terrific then. He looked like a force of nature.

All the major changes are in place. I don’t think he’s going to change any more for this one fight. He’s 36, what he’s doing has been working most of the time. I just think he’s going to set a pace, he’s going to do it on work-rate, and all out aggression.

It might mean this is the last time we are going to see him in a boxing ring, so he’s going to give it every last ounce that he has.

One of the things that surprises me about this fight - the public have been screaming for it for years, but the fighters haven’t been screaming for it. Suddenly, Manny is screaming for the fight, Manny is taking the short end of the purse, he's bending over backwards in every department to get it made.

Manny has agreed to everything. Why? I’ve got a slight little thought in the back of my mind that this could be Manny’s pension fight. It doesn’t mean he’s just in it for the money, it might mean the opposite.

It might mean this is the last time we are going to see him in a boxing ring, so he’s going to give it every last ounce that he has. If it is his pension fight, it doesn't detract from the fight.

One of the big differences between the two fighters is that Manny boxes for a nation, for his people. Floyd has a huge ego, boxes for himself and for the money.

He even calls himself ‘Money’ Mayweather, so that pretty much sums him up. In the last few rounds of a really hard fight, when fighters sometimes need something just to give them that extra spurt, boxing for your nation will give you that rather than boxing for your money or your ego.
