Victor Troicki has said that he is confident of another upset, ahead of his Australian Open third-round clash with seventh seed Tomas Berdych.

Troicki beat 26th seed Leonardo Mayer in the second round, and he has said that he is looking forward to his match with the former Grand Slam finalist.

He told reporters: "I'm confident, definitely, having a title before and coming into this event I'm playing good, I feel good, I'm just looking ahead one match, focusing for the next match. [Berdych is] one of the top players. I played him a lot of times, he's definitely very strong."

Troicki missed last season after he received a one-year doping ban.
