Sydney coach Paul Roos has urged Barry Hall to forget about his stats and just keep on terrorising defenders in Sunday's clash against Port Adelaide at the SCG.

The Swans spearhead rebounded from a frustrating match in Geelong with a menacing five-goal performance in Saturday night's home win over West Coast.

Roos said he wanted the fiery forward to keep on throwing his weight around in a sign the coach has regained full confidence in Hall keeping his notorious temper in check.

"With Hally, all he needs to do is just keep on focusing on that physical stuff," he said.

"Guys, particularly when they are closer to the end then their start (of their careers), it is easy to ... not panic but focus on things like marks, kicks, handballs.

"He showed on the weekend that he is a very, very good player.

"Look he might have only kicked two goals on the weekend. He might have kicked 2.3 but he kicked five straight which obviously helped his performance.

"I think if he just keeps focusing on that chase and the tackle he will be an impact player for us, there is no question."

Roos said the likes of Hall and Brisbane enforcer Jonathan Brown have the ability to really shake up defenders.

"When you have a power forward like a Jonathan Brown that tackles and chases that does make the guys around them nervous, no matter who they are," Roos said.

"They are big, strong, powerful guys and all those guys are quick.

"You can also hear them coming so that doesn't hurt either."

The ninth-placed Swans (4-4 win-loss record) need to maintain their strong home form against the Power before taking on the Western Bulldogs (Manuka) and reigning premiers Hawthorn (MCG) in the coming rounds.

Rebounding defender Nick Malceski is in line for a recall after being dumped from the side that beat the Eagles by five points at ANZ Stadium.

The runner-up in the club's 2007 best and fairest has struggled to regain top form after undergoing ground-breaking knee surgery early in 2008.

Roos said Malceski had impressed in the reserves on the weekend.

"He had a good game on the weekend, I think he kicked four goals and had 30 something possessions ... he certainly has to come into consideration," Roos said.

"He's done everything we have asked him to do."

There is a question mark over the fitness of Swans defender Lewis Roberts-Thomson (buttock).
