MELBOURNE is still optimistic of retaining Brad Green, but the versatile Demon has yet to make up his mind on his playing future.

On the third day of the exchange period, Melbourne general manager of football operations Chris Connolly said the club was still waiting to hear of Green's intentions. 

"Nothing's happened on the Brad Green front," Connolly told melbournefc.com.au.

"We know that Collingwood and Sydney have spoken to him and we want him to re-sign here [at Melbourne] at that's where it's at.

"So we're hoping he commits to Melbourne."

Connolly said the club will need to know what Green is doing before Friday.

"We'll need to know tomorrow night [Thursday]; one way or the other," he said.

"I haven't spoken about a deadline."

Connolly said Fremantle ruckman Robbie Warnock and Geelong midfielder Brent Prismall were still priorities for the club.

"We've certainly got our toe in the water with those two," Connolly said.

"So we're pretty keen to keep pursuing those two and we're certainly in the hunt.

"We've certainly spoken again and reinforced our position and it's pretty positive."

Connolly didn't expect any deals to be confirmed on Wednesday night.

"It'll all start to hot up tomorrow night. Carlton and Fremantle are going to mediation [with Robbie Warnock] and we'll see what comes of that, but we're certainly in the hunt."

"We're still working through [what we would in exchange for Warnock]."
