Jeff Fenech believes Anthony Mundine doesn't know how to use his speed advantage over Danny Green and 'The Man' is not yet a complete fighter.

Mundine and Green finally meet in a much anticipated matchup at Sydney's Aussie Stadium on Wednesday, in a World Boxing Association super middleweight eliminator.

Fenech trained Green for his first 21 professional bouts before the fighter opted to link with Cuban trainer Ismael Salas.

He said he expected his former charge to "kill" Mundine, though he believed the 'Man' had one advantage.

"If there's one thing that Mundine's got on Green, it's speed, but I don't believe he knows how to use his speed properly," said Fenech, who will not attend the fight as he is currently in the United States preparing Vic Darchinyan for his June 3 flyweight world title defence in Las Vegas against Mexican Luis Maldonado.

"To me, he's not a complete boxer yet. He's a long way off knowing how to use his speed and his whole body co-ordinated for that use."

Fenech warned Green would need to improve on his most recent outing last December, when he outpointed Mexican Kirino Garcia.

"The last fight, he just went through the motions, if he does that against Mundine, Mundine will beat him," Fenech said.

"If he's the old Danny Green, then Danny Green will win."

Fenech, who fought in front of a national record boxing crowd against Azumah Nelson in Melbourne in 1992, was unimpressed by the hype promoting the Green-Mundine fight as the biggest in Australian boxing history.

"Both of them have never ever been legitimate world champions," Fenech said of Mundine and Green.

"Anthony Mundine won a title made when the champion was made a super champion and then lost it against a guy who wouldn't get a two out of 20."

Fenech steered Green to an interim version of the World Boxing Council super middleweight world title, but the latter lost his two challenges to Markus Beyer for the fully fledged WBC championship.

Mundine and Green have never met in public view, but will be unable to avoid each other at Tuesday's weigh in.

"They'll have to be present when the other gets on the scales," WBA supervisor Derek Milham said.

Green's manager Justin Manolikos didn't expect his fighter to get involved in any theatrics with Mundine at the weigh in.

"Dan has got a job to do and it's time to let the fists do the talking," Manolikos said.

Asked about Green's mood, Manolikos said: "He's starting to get a little bit grumpy as you can imagine, but he's all good and taking it easy. Training has tapered right off and he's ready to go."

Green concluded his sparring last weekend.

"He's sharp, everything he can do for the fight, he's done," said world ranked middleweight Sam Soliman, who sparred around 60 rounds with Green.

"You just hope that you can bring that out on the day of the fight."

Manolikos said he was still hoping for a crowd of over 40,000 for the fight, with a favourable weather forecast for Wednesday.

"They assure me it's weather fine, track good, 23 degrees," Manolikos said.

He expected around 2000 West Australians to travel to Sydney to support Perth-born Green.
