Roger Federer is arguably the greatest male player to have ever picked up a racket and has a record 20 Grand Slam titles.
There have been increasing questions about when the current world No 2 will retire, with Federer giving very little away.
He is currently preparing for the Laver Cup, which begins tomorrow in Chicago.
Backed by his own sports agency Team8, Federer set up the tournament last year to allow the world’s best singles players to compete alongside each other in two teams of six.
There was initial scepticism over the event but it got off to a flying start as players really bought into the tournament.
It has already been announced that next year’s Laver Cup will be held in Federer’s homeland with Geneva hosting the event.
And Federer has admitted there is a possibility that he will take part in that event.
“I’m very happy to pack up and give my spot to somebody else if I wouldn’t deserve it anymore.
“Of course when I retire things will change and I honestly don’t know if I will be involved in the Laver Cup anymore.
“The idea of the Laver Cup was to bring all the generations together to have a good time and learn from one another.
“If I can be involved down the road then sure, I’d be very happy.
“Looking ahead to next year when the Laver Cup is going to go to Geneva, my home country.
“That was not the idea, it’s just happened that this European city has a big appetite for tennis. They said they tried really hard to get the Laver Cup and I knew it would be beautiful.
“There is a chance that I can still play there next year, so I’m just thrilled that it’s Geneva and I’m thrilled the Laver Cup is doing so well.”
While it may seem that the Laver Cup in Geneva could be Federer’s farewell, former world No 7 Barbara Schett believes the Swiss star will keep going until 2020.
When asked about Federer’s future, Schett said: “His peak goal is to still be playing Olympics once again.”
