Aggressive forward Barry Hall will replace defender Leo Barry as Sydney's captain in Saturday's AFL match against Carlton at Telstra Dome.

Sydney coach Paul Roos announced Hall as the new skipper as part of the ninth-placed team's rotation of six players to share the role following Stuart Maxfield's decision earlier this season to step down for family reasons.

Roos said he was confident the tattooed, shaven-headed former junior boxer would provide a good example on the field, despite Hall's lack of captaincy experience and occasional brushes with the AFL Tribunal in past seasons.

"We've seen the way Kirky (Brett Kirk) and Leo have responded around the club (to the captaincy role). Barry's demeanour now on the field is calm and I think it can only help," Roos said.

"Hopefully he doesn't change his game too much and just focuses on the team things that make him a really good player."

Hall said: "I'm pretty excited and very honoured. I've never been a captain, ever, even in junior days."

Sydney's leading goalkicker for the past three seasons, Hall was named in last year's All-Australian side and won the club's best and fairest award.

The 28-year-old former Saint said he did not plan to make any major changes to his playing style.

But Hall admitted to showing disappointment with the lack of opportunities in Sydney's forward line last week, with the side producing only 29 inside 50s in its 43-point loss to St Kilda.

"It does get frustrating. That's just the team game we've got to play, I can't be doing that sort of stuff," Hall said.
