Sydney midfielder Dan Hannebery has conceeded he is playing through some pain but says plenty of other footballers do the same thing.

Hannebery, like plenty of his experienced teammates, hasn't had his usual impact in the Swans' disastrous 0-6 start to this year, with the prolific ball winner well down on form.

The winger averaged 30.8 disposals per game last season on his way to a third All Australian jumper, and finished runner-up to Josh Kennedy in the Swans' best and fairest.

But Hannebery has reached that mark just one from the first six games, and hasn't shown the gut-running power he's been renowned for across a 176-game career.

His 23.2 possessions per game this year is his lowest average since 2011.

Hannebery failed to train with the main group on Wednesday at the SCG, and while a report on Channel Nine on Thursday night suggested his slow start to the season could be attiributed to struggling with osteitis pubis, he rejected the claims.

"I don't know how that came up, I've had a few niggles here and there, but so has every other player in the competition," Hannebery said.

"I've been 100 per cent fit to train at our main sessions and play, and feel really good going into games, so from that perspective I'm fine.

"My running during a game hasn't been affected by any niggles or injuries or anything like that.

"My form has been inconsistent at best, and it's been really disappointing, and like the rest of the group, especially the midfielders, I'm working hard to rectify it."

The 26-year-old hasn't been alone when it comes to a drop in his usually elite performances, with new captain Kennedy and fellow vice-captain Luke Parker also down on their average output.

Hannebery said the criticism of Sydney's star band of onballers has been warranted.

"Last year we were able to be play some strong footy and be really consistent throughout the whole year, and there wasn't too many games where the group was down," he said.

"This year we've had good quarters here and there, but we haven't been able to consistently come off the ground and say 'we beat the opposition midfield'.

"It's disappointing. It falls on everyone, and certainly I'm a part of that.

"Myself, 'Joey' (Kennedy), 'Parkes' (Parker), we're all working hard during the week to give ourselves the best chance to perform, but we haven't had the impact we would have liked."
