Stan Wawrinka insists he is playing
better than he was when he won the Australian Open a year ago, but feels his opponents have also improved.

The defending champion progressed to the semi-finals at Melbourne Park with a 6-3 6-4 7-6 (8-6) victory over Kei Nishikori on Wednesday.

Such a comprehensive win was unexpected, with Wawrinka hitting 46 winners in a good display on Rod Laver Arena.

Asked if he was reaching similar levels to 2014, the Swiss star said he was surpassing them.
“No, I think I play better,” Wawrinka said.
“But I think we all improve every year. I’m more aggressive. I’m more confident with my game when I come to the net.
“Again, it’s a grand slam. You play every two days.
“Today was a great level, was a great match. Now I’m going to enjoy a little bit, watch who’s going to win tonight and get ready for the semi-final.”
