Roger Federer has never been much of a rebel, but at next year’s Australian Open he is encouraging ballkids to break their golden rule.

In a video message sent to the 380 children who will officiate at the 2016 tournament, Federer encouraged ballkids to approach him for photos and signatures – something that is strictly not allowed by organisers.

“I was one of them (ball kids), I used to love chasing players down for autographs or pictures,” he said.

“I’m not even sure if you’re allowed to do it, but if you’re not, you can always ask me. I’m totally cool about it.”

Given the former world No.1’s nice-guy image, the message comes as little surprise, however tournament director Craig Tiley told NewsCorp being so accommodating might not be as easy as Federer thinks.

“It’s no surprise he’s willing to be approached by the kids for a selfie – he’s incredibly generous and always makes time for his fans.

“But with more than 380 in the Australian Open Woolworths Ballkid Program it might be a little ambitious, and we will rely on their outstanding professionalism to not break any rules.”
