At the 2018 Next Gen ATP Finals, one of the additions will be the towel rack at the back of the court that will be used by players so that ball boys do not need to bring it to them every time. Roger Federer was unsure about if this rule could work on the professional tour as well.

'I think the idea of having the ball kids bring it to you is to speed up the points, in between. If now you've got a hook or a rail in the back, I don't know. It's like are you wasting extra three seconds of time each and every point? Which doesn't sound like a lot, but you add that over a five-hour match, next thing you know, you saw much less tennis and this match could have ended four-and-a-half hours earlier maybe or like a half an hour earlier,' Federer said.

'Sure, try it out. See what happens. But it is true that all the players nowadays almost have towels just because it's gotten more intense. Maybe we sweat more. I'm not sure what the deal is. Also for guys to relax quicker their mind.

Maybe they feel like having the towel is something that brings them down. But I think the idea of having the ball kid bring it and take it away from you again is to really save time so you don't have to walk so far back and come back again.

I think that's the idea. So we'll see.' ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
