Roger Federer on Hingis retirement and was it love all between them at one point

Roger Federer has said he’s not sad to see compatriot Martina Hingis is retiring. Hingis announced on Thursday that she will cease playing following the WTA Finals in Singapore.
It will be the third time the 37-year-old Swiss former Wimbledon champion has called time on her career – but this time she really means it. ‘I think now it’s definite,’ said the now-doubles-specialist. ‘It’s different, because before I walked away thinking I might come back.’

The pair were rumored to be more than just friends
Federer used his press conference following victory over Benoit Paire at the Swiss Indoor tournament in Basel to say how influential she had been on his career. ‘Martina was partially the one who showed me how it was all done,’ he said on Thursday.
‘It was great for Switzerland to have someone of her caliber. We were very lucky. I loved playing with her at the Hopman Cup, she was always super friendly, I love that about her.
Rumors however have suggested that the pair were more than just friends for a period. Speculation has long suggested the two had privately seen each other on a romantic level for some time. Sources close to Hingis have alleged that a long time affair between the two players did exist and that Hingis is still very much in love with Federer.
The body language, eye contact and flirtatious behavior between the two paraded openly on court often has strongly hinted that the two were doubles partners on and off the court.

It was love all between the two for a time
Federer went on to explain why he wasn’t sad at hearing the news that Hingis’s career was about to be over. ‘I’m not sad to see her retire, she’s been in the game for long enough, she seems at peace with her decision – that’s wonderful. ‘I’ve always been a fan of her and I always will be.’
If rumor or speculation is anything to go by, it probably isn't game set and match for the two Swiss aces.
