Tennis legend Roger Federer has dropped a huge hint of retirement, admitting that he has been sidelined for the past 12 months

with a knee injury that has seen him enjoy the day-to-day aspects of fatherhood. The Swiss maestro, 40, has four children,

and while he admitted he missed traveling the world, the change in lifestyle was refreshing.

"I can honestly say that I am very happy at home," Federer told the Dutch newspaper Algemeen Dagblad.

“Sometimes we (the family) miss travelling, and of course I miss sport too, but life at home is good too.

"The tennis itinerary was sometimes excessive, especially when we had to organize it for the children as well.

But Federer, who dropped out of the official ATP Singles rankings for the first time in 25 years this week, has no intention of keeping his racket in the closet forever.

He has had three knee surgeries and will play in the Laver Cup in September. Federer then set his sights on a return to the ATP Tour in Basel in October.
