ST KILDA stopper Clint Jones won't be told who of Collingwood's star midfielders he'll be expected to blanket until later this week, but he knows a big task awaits him in Saturday's grand final.

The Saints' chief tagger has played on Alan Didak and Dane Swan in the past, though Scott Pendlebury's finals form making him a potential target as well.

The 26-year-old has enjoyed another successful season running with the AFL's best onballers, and he said whoever he mans, support from his teammates and an ability to work off his opponent would be critical.

"Usually I'll speak to the coaches Wednesday or Thursday and they'll give me a hint as to who I might be playing on," he said.

"I'll go through some vision with them and work out ways to stop them getting the ball and work off them as well.

"I've matched up on Swan and Didak before, so maybe one of them.

"Collingwood have been in great form this year and those two players in particular have had fantastic seasons, so I'll just wait and see and look forward to whoever it might be."

Jones had the job on Gary Ablett in last year's grand final, and he said there were similarities between tagging the star Cat and Collingwood's Swan.

"They're both really good players, very dangerous around goal, and their strength is through their hips, breaking tackles and that sort of thing," he said.

"In many ways I think they're very similar. With Gaz, getting through packs is his strength, and Swanny's sort of gut-running is his strength.

"They're different players but have some of the same strengths."

While Jones will prepare for a long day of burst running against Swan, he can expect to spend a lot more time in the enemy forward line if he lines up on Didak.

"If I play on Didak that's more of a defensive role … so you prepare a little bit differently," he said.

"I've been taken deep forward or deep back a number of times, playing on (Brent) Harvey and guys like that. So I'm pretty comfortable going forward also."

Jones, who trained away from the main group on Monday, said he had no injury concerns and would take part in the remaining two sessions this week.

After 72 games, he said he no longer got nervous about playing on high-profile opponents, but was wary of Saturday's stage.

"Every player I've played on this year, I've had terrific support from my teammates as well, so I rely on them heavily," he said.

"As time goes on it becomes normal, you know you've got a really good player and I'm generally pretty relaxed before the game. This week might be a little bit different."
