Roger Federer could announce his retirement at the Swiss Indoors later this year, according to tennis writer and Federer biographer Simon Graf. Federer turns 40 in August this year and has struggled with injury problems in the last 12 months. The 20-times Grand Slam men's singles champion underwent two separate knee surgeries and he will miss the Australian Open next month as he continues his rehabilitation. Graf says perhaps Federer does not even know himself when he plans to retire but the Swiss Indoors could be the time where the inevitable happens. The tournament takes place in Federer's birthplace of Basel between October 23 and October 31 this year. “I mean, we don’t know. I don’t think Roger Federer knows himself," Graf said. "I mean, I know he’s far from where he would love to be right now. "In terms of form, tennis-wise, he alone (knows), the grip, go-back, get-back to the court, when he really feels he can play at a certain level. I don’t think it’s important where (at which event) he steps away from the game. I did an interview with him after he won the Australian Open (in) 2017. "I met him up in the mountains in Lenzerheide, where he has his second home. And he said, ‘my career has been so corny, like, everything has been so amazing. I don’t need a corny finish or like, it doesn’t matter how it will happen'. “It will happen sometime… Maybe he will announce (that) he will step away from the game in Basel, maybe. I don’t think it’s important for him where he steps away."
