Football Federation Australia's mooted 'Cup' competition needs to start sooner rather than later according to Fox Sports pundit Mark Bosnich.

An FA Cup-type arrangement needs to be introduced to Australian football to add a new dimension and get the old fans back says the former goalkeeper.

"You can't beat the romance of a cup competition," Bosnich said on Fox Sports FC.

"However it's going to be, let's just get it started. One main thing we need to do is bridge the gap between this so called 'old soccer' with 'new football'.

"I don't even want to hear 'old soccer' or 'new football'. I just want to hear football or soccer for eternity.

"This is one way to bridge the gap. There are still too many people from the past who are afflicted by what went on in the establishment of the A-League. We need to get them back on board."

Melbourne Heart captain Simon Colosimo agreed wholeheartedly with Bosnich's sentiments: "I'm all for the cup," he said.

"I think it would be quite daunting going to Melbourne Knights' stadium.

"I did that as a youngster ... I'm older but I'm still going to be scared going out there.

"There's a lot of history in quite a few of those clubs. It'd be great to have them play against the elite and the possibility of winning something. And if it means (an AFC Asian) Champions League spot, the possibility of moving on."

But Mike Cockerill said it was important that FFA did not turn this new Cup idea into a league format.

"If they go with the group stage then they've lost me," Cockerill said.

"A cup is a knockout.

"It's the (UEFA) Champions League and not the European Cup because they went to a group stage.

"We don't need that in this country. I don't want to have a comp that virtually guarantees the A-League clubs dominate.

"I want the chance of Sydney United knocking off Sydney FC or Melbourne Knights knocking over Melbourne Victory, and that's only possible in a one-off situation."
