Federer, 41, ends his professional career with play in the Laver Cup.

Now it appears that the Swiss superstar's last top match will be in doubles - and he hopes to play with friend and rival Rafael Nadal. 

Together, they have 42 singles titles in the grand slam context, 20 of which Federer has won.

"The children have been fussing"

Recently, Federer shared the news that he is retiring as an elite player.

In an interview with the Swiss newspaper Blick, Federer shares his, and his family's, thoughts on the decision to retire.

- This has been a process for the whole family.

The last few years have been very tough for me, but even tougher for Mirka.

For her, it is a great relief that it is all over.

The kids have always been nagging me to stop playing so we can go on more ski trips, but when I told them I was quitting, three out of four started crying, he says

Federer also reveals that he decided to retire already last summer, after a loss to Hubert Hurkacz at Wimbledon.

Since then he has not played at the top level.

Got worse and worse

- After that match I told the crowd that I hope to see them again next year.

Then and there I believed it.

But in the days and weeks that followed, the knee just got worse and worse and I realized it wasn't going to work.

It was very emotional when I realized it was over, he says.

Although Federer's professional career is about to end, he does not intend to retire from tennis for good.

Federer is open to both charity matches and working as an expert commentator on television in the future.
