RENOWNED TRAINER Angelo Dundee believes Oscar De La Hoya has the perfect style to beat Manny Pacquiao in their highly anticipated welterweight clash tonight.

Dundee, who has trained such greats as Muhammad Ali, Sugar Ray Leonard and George Foreman, advised De La Hoya during his training camp.

"We found out stuff he can do against Pacquiao," Dundee said. "Exactly what we did, that's our business, and you'll see on Saturday night."

But Dundee acknowledged Pacquiao, 47-3-2 (35 KOs) presented unique challenges.

"Nobody fights like Pacquiao," he said. "He's got his own style, he's an awkward guy, and he's a busy guy."

Pacquiao's trainer, Freddie Roach, said De La Hoya, 39-5 (30 KOs) would struggle with Pacquiao's fast-paced, aggressive style in Las Vegas.

"Manny Pacquiao's one of those fighters who's very hard to read," he said. "He doesn't do usual things. He throws punches from odd angles, you don't know where he's coming from."

Dundee said Pacquiao would be especially vulnerable to De La Hoya's vaunted left hook, and Roach acknowledged that was the punch he was keen to avoid.

"I think Manny can take his punch, yes, but we're planning on not getting hit by the left hook."

Roach dismissed concerns that Pacquiao, a Filipino whose first professional fight was at 106lb, more than 40lb lighter than he will weigh tonight, would be at a disadvantage against the bigger De La Hoya, who has won world titles from super featherweight to middleweight.

"I don't think size wins this fight, I think speed does," he said.
