Sydney Swan Luke Parker has warned Melbourne’s Bernie Vince that the Demon tagger is in for ‘a hard day’ if he gets the job on teammate Dan Hannebery.

Hannebery is ranked second in the competition for disposals after five rounds, averaging over 31 per game, and has been one of the few Swans to produce consistent footy in 2015.

Vince has done some of his best work as a run-with player this year, most notably in round three against his former club Adelaide, when he kept Patrick Dangerfield to just 16 possessions.

The physical tactics employed by Vince against the Crows made headlines, and Parker says the Swans must be ready to rally behind Hannebery at the MCG.

"I think the main thing is we don't leave it up to 'Hanners'. I think the main thing is we let him (Vince) know he's in for a hard day, and hopefully 'Hanners' can get free," Parker said.

"We don't just want to worry about our own game, we want to look around and help each other out."

It’s possible that Parker, the reigning Swans' club champion, could find himself with the Vince shadow on Saturday night.

On the back of a brilliant 2014 season when he played every game on his way to winning the Bob Skilton Medal, Parker has carried that form into the opening five rounds.

At 22, Parker is the youngest player to be elevated into the Swans' leadership group, and he's noticed the extra attention coming his way on the field.

"I kind of expected that, I'm a one-on-one player anyway so most of the time I'm on someone around stoppages," Parker said.

"It strips it back to a one-on-one game if you're getting tagged, so I don't try to confuse or over-think things out there."

Isaac Heeney (ankle) moved freely at Swans training on Thursday, while defender Sam Reid (calf) went through some running drills away from the main group before the session was closed to the media.

The pair both missed last week's shock four-point loss to the Western Bulldogs at the SCG.
