MELBOURNE coach Paul Roos would baulk at showing a player from a rival around the club mid-season as part of any recruiting bid.

And Roos is adamant the AFL must not adopt the NRL model, where players can say months in advance that they will play elsewhere the following season.

The Demons coach was reacting to news that Collingwood last week gave Western Bulldogs onballer Lin Jong a tour of their facilities.

Jong is coming out of contract and he met a Magpies official at the building after hours.

"Would I bring a player here? No. Everyone is going to have different views on it," Roos said.

"We saw the Geelong boys fly a couple of years ago, and in hindsight I think they said they probably shouldn't have done it," he said, referring to Cats players travelling to Adelaide in an unsuccessful bid to woo Power star Travis Boak to Geelong.

"It would be interesting to see Collingwood's view on the back of the publicity," Roos said of the Jong tour.

"All I'm saying to you is I wouldn't bring a player into the club with eight or nine rounds to go – I can only speak for myself."

The Melbourne coach said clubs were well aware that discussions were being held with managers – and even players.

"If you're a player, you're out of contract, you have a right to work out where you're valued – I think we're all comfortable with that," Roos said.

He was adamant that if he knew a player was going to leave Melbourne, he would not play him.

He pointed to former Demons player James Frawley, with Roos saying the defender's attitude was faultless in the lead-up to the move to Hawthorn.

"What I would have a problem with, having lived in Sydney, is the NRL system," Roos said.

"It just doesn't work.

"And that's the other extreme.

"What we're talking about I guess with Lin Jong is somewhere in the middle, and we're all going to have different views on that."
