Australian 4x400m relay runner John Steffensen has had a dig at his own team after its poor performance in the first round at the track.
In a post-race interview with the Nine Network, Steffensen said he had to do well because others didn't.
"It's a team effort and unfortunately you have to make up for some that aren't doing well," he said.
When pressed about his own performance and attitude, the Athens silver medal winner didn't hold back.
"I battled today," he said.
"I'm an inspiration to those out there in this world that are out there that may be battling and doing it tough."
His earlier public bitterness at being overlooked as Australia's lone individual 400m runner is well documented.
Yesterday his team mate, London 400m finalist Steve Solomon, was confident of Australia's chances in the relay as they attempted to qualify for a third straight Olympic men’s 4x400m final.
The 19-year-old said he was proud of his achievements at the Olympics and had proved his worth in the role.
"Personally I wouldn't have gone the same path John did," he said.
"We should build that team chemistry and come together as one."
The Aussie team of Steffensen, Solomon, Ben Offereins and Brendan Cole finished fourth in the heats and will miss the final unless other teams are disqualified.
