Promoter Frank Warren insists Manny Pacquiao needs to go rough on Floyd Mayweather
Manny Pacquiao will have to go for broke, according to promoter Frank Warren, if he is to pull off the win of his career tomorrow night when he clashes with Floyd Mayweather in a showdown which has captured the imagination of the sporting world.
Top promoter Warren believes that Mayweather starts favourite in a blockbuster clash - which is expected to see the top two fighters of their generation split around £300m - as the timing of the welterweight clash clearly favours the Money man.
Pacquiao has had some very tough fights in recent times, while Mayweather has smoothly extended his unbeaten record to 47, though, as Warren points out, his first fight with Marcos Maidana last March gave an insight in how his first loss may come about.
Warren said: "If Pacquiao is going to win he has to get inside and rough up Mayweather - take him out of his stride and really out-work him close up. You saw the way Maidana took Mayweather out of his stride and he didn't like it and it was effective, so Pacquaio has to do something similar.
"He's the one who is going to make the fight because Mayweather will do his thing as he always has. He won't get carried away with how big the fight is, he will stick to his plan - so it's up to Pacquiao to take it to him.
"But Mayweather is just so slick and he's the fresher of the two at this stage. He hasn't been in too many hard fights so I think he has the edge and I can see him winning on points or it's even possible that if he starts to get through to Pacquaio he could even stop him late on."
Mayweather, the highest paid sportsman in the world, has often been compared with great fighters of the past and in particular those of the late 1970s and 1980s - such as Tommy Hearns, Sugar Ray Leonard and Roberto Duran. While Warren views him as "the best fighter of his generation" he says it is difficult to make a judgment on Mayweather's standing beside other legends.
Warren added: "That era of Hearns, Leonard and Duran and other guys like Carlos Palomino and Pepe Cuevas around the same time was just extraordinary, we were spoiled them. There was a greater quality in depth in that group and Mayweather hasn't had to face fighters like that. Someone like Leonard was beating other legendary fighters.
"But he is the best fighter of his generation, not the most exciting but the best and he has beaten everyone who has been put in front of him so you can't much better than that."
Pacquiao's promote Bob Arum Bob Arum believes Mayweather's declaration that he will soon retire after sensing the unbeaten American has fallen out of love with boxing.
Toppling Pacquiao at the MGM Grand would register a 48th victory and leave him just one short of equalling Rocky Marciano's hallowed 49-fight unbeaten mark.
Mayweather's insistence that he has no desire to eclipse Marciano has been met with widespread scepticism but Arum, who promoted the reigning pound-for-pound king for the first decade of his career, predicts he will soon hang up his gloves.
"I believe what Floyd is saying in that he is looking towards retirement. He's been at it since he's eight years old and he doesn't enjoy it like he used to," Arum said.
"Like Marvin Hagler said, millionaires sleep in silk pyjamas and don't like to get up in the morning and do roadwork.
"When he retires, I think Floyd will be a great party guy. He'll have plenty of money and he'll enjoy himself."
Meanwhile, Warren is keeping his fingers crossed that he can come to an agreement for number one challenger Tyson Fury to face World heavyweight champion Wladimir Klitschko.
"The WBO have ordered a 30-day period of negotiations and the WBA 60 days. We are in ongoing talks, we're apart on a couple of things but hopefully we can get it done. It would be a huge occasion, the World heavyweight title is the blue riband event," he said.
