"The Filipino Flash" is ready for the "Raging Bull" and vice-versa. But the ultimate question remains: when, if ever, will the fight be held?

This, at least, is the biggest question to date between Nonito Donaire Jr. and Vic Darchinyan after the Filipino fighter's sixth round TKO win against Moruti Mthalane in Las Vegas over the weekend to retain the IBF/IBO flyweight belts and the Australia-based Armenian's decisive victory against WBC/WBA “super champion” Cristian Mijares in Carson City, California.

In a telephone interview, Donaire told Manila-based sports analyst Ronnie Nathanielsz that he is ready to face Darchinyan "anytime, anywhere."

Donaire's reaction was based on a Darchinyan promise that said, “I will destroy Donaire, even easier than I beat Mijares”.

But for Darchinyan handler Gary Shaw, "He (Donaire) has no chance, no shot."

"There should be a price paid for total disloyalty. I gave him a shot against Darchinyan, he won the title fair and square and then he turned against me for no reason. And today, had he stayed with me, his next fight would've been for three world titles at 115," said Shaw, who until early this year handled Donaire's career.

After beating Darchinyan in July last year, Donaire's career was put in the freezer up until Arum stepped in.

Arum had told Nathanielsz that he is planning to venues in Manila or Macau for his ward and the possibility of fighting  WBA interim champion Jorge Arce or WBO champion Fernando Montiel. Fight plans have yet to be finalized as of last report.

On Saturday, Darchinyan knocked out Mijares in the ninth round to unify the super flyweight world title in dominant style.

Darchinyan, the International Boxing Federation champion, knocked Mijares down in the first round and finished him off late in the ninth with a big left that put the Mexican fighter flat on his back.

Referee Lou Moret began to count, but when he saw Mijares was barely moving he waved the fight over at three minutes of the ninth.

Darchinyan added Mijares's World Boxing Council and World Boxing Association 115-pound (52.1kg) titles to his IBF belt, becoming the first fighter to hold all three in the class.

Armenian-born Darchinyan improved to 31-1-1, with 25 knockouts.

The 32-year-old southpaw went into the bout as an underdog, but had vowed to knock Mijares out. To that end he started aggressively and displayed power that Mijares was unable to find an answer for.

In Las Vegas also on Saturday, Donaire retained his International Boxing Federation flyweight world title with a sixth-round technical knockout of Mthalane.

Referee Joe Cortez stopped the fight at 1:31 of the sixth after Donaire had opened a cut on the inside of Mthalane's left eyelid.

Donaire improved to 21-1 with 13 victories inside the distance, while Mthalane fell to 22-3, with 15 knockouts. With reports from Steve Kim, Maxboxing.com and Agence France-Presse
