Roger Federer’s large family comes with him to most tournaments and play a key role in his schedule.
Federer and his wife Mirka have two sets of twins, who are regularly spotted at tournaments when the 20-time Grand Slam star is competing.
They were absent from his trip to China for the Shanghai Masters and exhibition match in Japan on Monday.
But they are likely to be close by next week when Federer competes in his hometown event in Basel.
The question of when Federer will finally decide to hang up his racket has been a constant topic of conversation in recent years.
However, the 38-year-old appears happy to continue playing as long as his family are happy
In an interview with China Global Television Network in Shanghai, Federer was asked how he is able to juggle his life on tour and family.

And the Swiss credited his wife for her support and insisted his children will determine his future plans.
“I think that’s the secret to make it work,” Federer said.
“Some other players don’t have family and so forth. So it is pretty straight forward, it is fairly simple.
“When I book flight tickets, we are sometimes buying ten tickets, 25 bags, convoy of cars, everything becomes so massive and so huge, which is fun but at the same time can be draining.
“It is a huge task. My wife chips in a lot of energy and a lot of know-how because she has also done it for over 20 years.
“So we need to be very careful and clever with my wife. How many tournaments to play, which one to play, where to take the kids, because you don’t want to miss a beat and then later you actually have a lot of regrets.
“As long as the kids have had a good time on the tour, it is also OK for me to continue playing.
“The moment I feel they are growing unhappy with the travelling I would obviously leave them at home more but it would also have an impact on my schedule because my family is my No. 1 priority, it’s always been clear for me.”
