Australian dual Olympic gold medallist Michael Klim admits he risks flopping in his return to competitive swimming and has no expectations.
Part of Australia's gold medal 100m and 200m freestyle relay teams in Sydney in 2000, the 33-year-old announced on Monday he was back and aiming for next year's London Olympics.
Also an individual world champion in the 200m freestyle and 100m butterfly events in 1998, Klim's career dipped after 2000, as a series of back and shoulder injuries took a toll, before his retirement in 2007.
However Klim says in recent times he's started training hard and his love and passion for swimming has returned.
But he was unsure whether that passion would be matched by results, saying he has no expectations and conceding he doesn't know if his body can handle it.
He follows fellow Australian swimming stars Ian Thorpe, Libby Trickett and Geoff Huegill onto the comeback trail.
