The 19-time Grand Slam champion is currently enjoying a really good spell in his career as he progressed to the last 16 of the Australian Open yesterday.
Federer, 36, will leave a lasting legacy on the game once he eventually decides to hang up his racket.
And he joked that he did not want his children to replicate his career because of the demands of touring across the world.
However, he did admit that he encourages them to take part in the sport – but who knows, could there be another Federer ruling the court for decades to come?
“I mean, I hope they don’t (take up professional tennis) just because we don’t need another 25 years on tour,” he said.
“I’m just a supportive parent. I can’t tell which direction they’re going to go.
“If there’s going to be anything in sports or somewhere in finance or business, I have no idea where they’re going to go.
“All I know is I’ll be incredibly supportive of them.”
Federer also revealed the reason why he encourages his children to participate in tennis.
“I’m happy they all do play tennis a little bit because basically literally all our friends who have kids as well, they all play tennis,” he added.
“I wouldn’t want my kids to be the only ones who don’t play tennis, so with my wife we have sort of a little requirement on things they have to do in their life, and tennis is unfortunately one of them.
“It’s not because we want them to. It’s because I think it would be a pity if they played no tennis at all.”
