Stanislas Wawrinka ready for "tough battle" with Tomas Berdych

Stanislas Wawrinka has conceded that he will have to overcome a "tough battle" with Tomas Berdych to reach the final of the Australian Open.

The Swiss player has been tipped to reach Sunday's showpiece event following his five-set victory over defending champion Novak Djokovic earlier today.

However, while the 28-year-old has accepted that he has a "big chance", he insists that world number seven Berdych will provide a stern test.

"It's for sure a big chance. Berdych is playing well since the beginning of the tournament. He's going to be a tough player to beat. He already made one final in a Slam. He already made the semi-finals in every Grand Slam. He's really close to the top, top guys. It's going to be a tough battle," he told reporters.

Wawrinka has won the last three meetings between the two players.
