Roger Federer wants to team up with Martina Hingis to represent Switzerland at the London 2012 Olympics.
"I might as well just see if she is available," Federer said. "If I played mixed with anybody it would be with Hingis just because she's been and amazing player and I had my first kind of success at the Hopman Cup with her and practiced and played with her before."
Federer won gold in mixed doubles with Stanislas Wawrinka in Beijing, but Hingis has only played occasionally since retiring in November 2007.
"Even if she is retired, she might think about it at least," Federer said. "I've approached her already a long time ago, and I guess she just mentioned something to the press and it took a life of its own.
"But I haven't spoken to her myself yet. We'll see where it goes. I know it's a lot on your plate to play singles, doubles and mixed. I need to decide if I want to do that in the first place, and then see if she will come out of retirement"
Hingis has won five grand slam titles, while Federer has won 16 slams.
