While Fenech prepares to help relaunch the career of Green's arch nemesis Anthony Mundine in the United States, the boxing legend said Australia could still witness Mundine vs Green II - should the WA fighter manage to string a couple of victories together.
But Fenech said he was sure Green would not retire - because he was too money hungry to retire.
Following his latest loss to WBC Cruiserweight champion Krzysztof Włodarczyk last month, speculation on whether the former Olympian will retire has been rife throughout the boxing world.
The loss was his second consecutive defeat, the previous coming from an Antonio Tarver knockout which saw Green drop the IBO Cruiserweight title in July.
Since his latest loss, the ‘Marrickville Mauler’ has called for Green to hang up the gloves for a second and final time since his short stint in retirement spanning just over 12 months between 2008-2009.
While Green spends the remainder of 2011 pondering his future, Fenech is unconvinced Green is seriously contemplating retirement when he can still command big money fights.
“To be honest I don’t really care what Danny green does,” Fenech told SEN Radio.
“He’s been stopped by who he says is the best cruiserweight in the world which he’s far from that if the guys who just beat him is the best I don’t know what that says about Antonio Tarver, it makes him god or something very special.
“Danny is very far from retiring; he can still make money easily.
“He’s got a great fan base here in Australia, especially in Perth and he’ll continue to milk money off his fans.
“If I was Danny Green’s trainer I would tell him you’ve got what you’ve wanted. You wanted one unit in Perth - he owns half of Perth now,” Fenech said.
“So maybe it’s time for him to retire.”
When quizzed on about his attack on the 38-year-old, Fenech defended his actions as retribution for all the times Green spoke about him behind his back.
“The story about me and Danny Green will one day come out," Fenech said.
“I can’t wait til the truth comes out about why Danny Green and I split and it was nothing to do about money it was just about being loyal and loyalty and that is the main thing I have tried to put in my life.”
Fenech was in Green’s camp the first time the two faced off in a unanimous points decision to Mundine in 2006.
“You never know if he does a few things off a couple of fights there might be an Anthony Mundine-Danny green fight two,” he said.
“I can honestly say Danny Green can’t handle speed and good boxing. He proved that against Anthony in the first fight and he proved it against Antonio Tarver.”
