Unlike always, this time Roger Federer's kids were dishing out tips for him.
After cruising into the Australian Open quarter-finals with a 6-2 6-1 6-4 victory against 15th-seeded Belgian David Goffin, Federer, in an interview, spoke about the advices he get from his twin six-year-old daughters Myla Rose and Charlene Riva, reports News.com.au.
The 34-year-old tennis champ spoke about the very unusual advice his children passed on to him to mix it up a little on court.
"Yeah, the one thing in tennis they tell me is I should ... play on the lines. They think that's a good thing. I was like, 'OK, I'll try that,'" the 34-year-old father of four explained.
"The other one said that maybe you should look that way and play the other way. I said, 'OK, I'll try that, too. It's not as easy as you think it is, but I'll try,' he added.
