In an interview to BBC Breakfast Novak Djokovic, Roger Federer and Rafael Nadal spoke about their rivalry and family life. The Serb said: "We have been on the tour for so many years, I do get to see these guys probably more than my parents."
Federer then spoke about fatherhood and said that Nadal, who got married to his longtime girlfriend Maria Francisca Perello last month, will be a good father. Then Roger revealed: "One of my kids was not feeling well and she was apologising to me.
'I am so sorry I am not feeling well' I am like, Don't worry that's what the parents are here for. If you are not feeling well, we will get up too. It's tougher when it's just before a semi or a final against one of my big rivals."
Nadal added: "I always thought that I was gonna stop my tennis career around 30s. Everyone said they were going to have a shorter career. But now I do not know. Maybe it's the time to start now, you never know."
But when will they stop competing? Djokovic said: "It's either all of us stop or none of us stop. That's what it seems like." Nadal and Federer did not start their ATP Finals campaign on a good note having respectively lost to Alexander Zverev on Monday and to Dominic Thiem on Sunday.
