After victories, there's nothing that Adam Goodes enjoys more than taking part in one of the great customs of Australian football, joining his Sydney team-mates in the singing of the club song.

But Goodes' pre-match routine couldn't be more different since his rediscovery of a far more private and personal ritual that he credits for helping to turn around his form this season.

It's meditation, something he was introduced to a few years back by the coach's wife, Tami Roos, along with about a dozen other Swans.

Goodes can't vouch for his team-mates, but swears by meditation as well as yoga which he practices twice weekly for helping to clear his mind and get his game back on track.

"Early in the season I wasn't in great form and I knew it wasn't because I wasn't fit or strong, it was just mentally I needed to deal with things a lot better," said Goodes on Wednesday.

"I was just clouded, going into games, in my mind ... but once I go into a game with a clear mind I know I can perform at a pretty good level and consistently ... and that came back to me starting meditation and really putting a lot of emphasis into that."

"It's just a matter of finding time some time in your day to do it."

"It's important, I value it and it's definitely helped me the last four or five weeks to go out there and do the things that I want to do on the field which has been pleasing."

Interestingly, Goodes puts the Swans' poor record on the road this season - they've lost every match away from Sydney and won every match at home - down to a 'mindset thing'.

If the Swans can get their heads right, he believes, and commit to a team effort, they have every chance of repeating their Round 2 defeat of Hawthorn when the teams meet again at the MCG on Sunday.

"Every time we lose we have a lot of inconsistent players," said Goodes.

"When we win we have good wins and everyone plays (well) and that's the way we've been known in the system for the last six or seven years."

"We do need everyone jumping on board (but) when we have five or six or seven or eight players who aren't jumping on board and helping the team, it severely affects us."

One of the keys to that early-season upset win was the Swans' control of the stoppages and ability to disrupt supply to the Hawks' trumps up forward, Jarryd Roughead and Lance Franklin.

Nine weeks on, according to Goodes, nothing's changed.

"That's the key," he said. "That's where the focus was the last time we played the Hawks - to really minimise the long ball and the space that their key forwards could have and I thought Craig (Bolton) and Lewis (Roberts-Thomson) did a fantastic job in matching-up on their two key players."
