SYDNEY Swans coach John Longmire is confident Adam Goodes has moved on from his missed goal attempt after the siren against Essendon on Saturday night.

Goodes took a mark inside 50m just before the final siren and with the Swans trailing by two points, giving the dual Brownlow medallist a chance to win the game.

But his set shot faded to the left, leaving Essendon the narrowest of winners, but it was a cruel outcome for Goodes, who was sensational in a losing cause.

Longmire believes Goodes will quickly leave the moment behind him, and continues to marvel at his co-captain's skills.

"I haven't seen Goodesy today, but I'm sure he's moved on," Longmire said on Monday.

"He's an experienced, professional AFL footballer, he's captain of our footy club; I thought his effort for four quarters was enormous.

"To see his speed, at 31 years of age, for a player who's played as much footy as he's played, to see him bursting through and opening up packs the way he's been doing it is a real credit to him.

"I just hope he's able to keep going for another few years and he certainly lights us up when he's doing it."

Two weeks ago against the Western Bulldogs, Goodes had a career-high 34 possessions and was best on ground, form he repeated against the Bombers.

Before and after the Essendon game, Bombers coach James Hird said Goodes was a nightmare for opposition teams to match up on, with his combination of size, strength and speed.

Longmire labelled him "a unique athlete".

"The last couple of weeks he's certainly playing as good as he has this year and probably for a couple of years," Longmire said.

"It was interesting, in the pre-season we tested him over 20m and he did a 2.89 (seconds) and was faster than Gary Rohan and Lewis Jetta and a number of those players on our list.

"You look at him at 31 years of age and a hundred kilos and I thought on the weekend you saw that real electrifying speed.

"His ability to do it again and again with repeat efforts, he's a unique athlete."

Longmire also reserved special praise for courageous 20-year-old midfielder Dan Hannebery - albeit a little tongue in cheek.

Hannebery was crunched when he went back into a marking contest with Essendon's Michael Hurley, but came back onto the ground after a brief break and was throwing himself into contests a few minutes later.

"There's nothing wrong with 'Hanners'. We don't know what's the matter with him. He's got to go a bit harder next time when he goes back into a pack - I thought he took a couple of backward steps,’’ Longmire joked.

"I think Daniel Hannebery was courageous bordering on being a maniac, his attack on the ball a couple of times during the course of the game.

"To go back in front of Michael Hurley, who's a big fella, get cleaned up the way he did, he went off and then came back on and in the first minute of coming back on did it again.

"Then his last quarter was enormous and he didn't use the heavy hit as an excuse, he just wanted to win.

"You can't wrap players enough who are not only courageous but just want to win and he's got it in spades,’’ Longmire said of Hannebery.

Hannebery is sporting a swollen eye and a badly grazed cheek today but is otherwise showing no ill-effects from his courageous acts against Essendon.
