Tomas Berdych has said that he is "looking forward" to facing Rafael Nadal in the quarter-finals of the Australian Open.

The Czech beat Australian Bernard Tomic in straight sets in the fourth round on Sunday to set up a meeting with the 2009 champion.

The seventh seed told reporters: "I'm feeling very good. It's been a great, great run so far. I just put myself in the best possible position right now.

"I'm just really looking forward to it. I'm going to have to add something extra again. That's how the tournament is developing, just move forward, just be ready for it. I'm feeling strong both physically and mentally. Just looking forward to the match.

"Every opponent, even if it is the same one, then the match is different. It's going to start from 0-0. That's how it is. No comparing with the past. Just trying to be in this time and looking forward to it."

Berdych has only been beyond the quarter-finals at the Australian Open once before.
