Hopman Cup tournament director Paul McNamee will step up plans to lure Roger Federer back to Perth after Lleyton Hewitt was locked in for a sixth time yesterday.
Hewitt will team up with world No.30 Jarmila Gajdosova for Australia, with French Open women's winner Li Na partnering Chinese teenager Wu Di at Burswood from December 31 to January 7.
Li, runner-up at this year's Australian Open, made history when she became the first Asian to win a grand slam singles title at Roland Garros this year.
McNamee said he would arrange a "face-to-face" meeting with Federer at the US Open after the 17-times grand slam champion expressed an interest in teaming with Martina Hingis in the mixed doubles at next year's London Olympic Games.
Federer last played the Hopman Cup in 2000-2001 when he and Hingis beat Jan-Michael Gambill and Monica Seles 2-1 in the final.
McNamee said Federer's interest in playing mixed doubles had created a "window of opportunity" after he had earlier turned down what is an annual invitation to Perth.
"I did get a no from Roger earlier in the year but given there is this story circulating that he will be playing mixed doubles at the Olympics with Martina Hingis, I certainly will ask the question again when I go to New York," McNamee said.
"They would be a phenomenal team, especially as they have won this tournament and Roger's first professional victory was in Perth."
McNamee said the chances of the dream pairing hinged on Federer, with Hingis keen to line up in her fifth Hopman Cup.
Hingis combined with Marc Rosset at Hopman Cup VIII and IX, Ivo Heuberger at Hopman Cup XI and Federer at Hopman Cup XIII.
"Martina has said to me that she would kill to come back here, she is a given," McNamee said.
Hingis dominated the tour from 1997-99 but quit in 2007 without contesting a positive test for cocaine after proclaiming her innocence.
Were she to seriously consider Federer's offer and a Hopman return, Hingis would have to make a return to the WTA (if only in doubles), make herself available for the Swiss Fed Cup team and also become available for doping tests.
Hewitt, who has been offered a wild-card to the US Open, said he was excited about returning.
"I'm looking forward to being 100 per cent fit," Hewitt said."For me, the Hopman is a great start to the year."
