SYDNEY Swans coach John Longmire believes Adam Goodes is returning to his best form and says the Brownlow medallist gave glimpses of this during Saturday night's 94-point win over the Greater Western Sydney.

Goodes was playing his second match since returning from a six-week layoff due to injury and he finished with two goals from four scoring shots, 15 possessions and four marks from about 90 minutes game time.

It was an improvement from the previous week against premier Geelong, where the 32-year-old was subbed off midway through the last quarter and managed just seven touches.

Longmire said Goodes got better the longer the game went and had a "pretty good" final term,. But the coach was unable to put a time frame on when Goodes would be back to his best.

"He started a bit quiet and I thought the last quarter he started to get some pretty good contests and win his one-on-ones," Longmire told reporters after the match.

"He was a lot better tonight than what he was last week."

"I'm hoping he will be better again next week."

After a sluggish start, the Swans dominated the second half, booting 11 goals to three, to run out 19.18 (132) to 5.8 (38) victors over their cross-town rivals in front of 22,565 fans.

Longmire said he urged the side's senior players to take control of the match in the third quarter and was pleased they responded to that challenge.

Brett Kirk medallist Kieren Jack said the response of the more experienced members of the team was critical to the fast start at the beginning of the third quarter.

"If your leaders stand up what ends up happening is your next tier starts to follow," Jack said.

Meanwhile, Giants coach Kevin Sheedy said the Swans were "a chance" of being legitimate premiership contenders in September.

"If they can keep away from injury the Swans have obviously got a great chance," Sheedy said after the match.
