The former world tennis number one Martina Hingis says she may make a second return to the women's tour, this time on the doubles circuit.
The 29-year-old Swiss, who won Wimbledon when she was 16, and picked up four other grand slam singles titles, quit the sport for a second time in 2007 but says she could be tempted back if she can find a partner.
Hingis has been playing competitively in the United States.
She quit the sport for the first time in 2003 at the age of 22, suffering from ankle injuries.
She returned in 2006 but quit again the following year under a cloud after she tested positive for cocaine and was suspended for two years but maintains her innocence.
