Bernard Tomic looks ahead to a time when Roger Federer and other aging players will give away to a younger crop of players in the sport's upper echelon.

“Generations will move on, for sure in two or three years there will be no Federers,” Tomic told reporters in previewing the Apia Sydney International, where he’s the defending champion. “They will slowly start moving and four to five years from now it will be a totally different group of players in the Top 10, that’s for sure. It gives a chance for players like [Milos] Raonic and [Grigor] Dimitrov and myself to get into that spot, and take over and dominate. I’ve got to stay positive, keep working, and my time will come to get to that stage.”
