Agnieszka Radwanska believes that she is playing her best tennis at the Australian Open.
The Pole came through a 6-1 6-3 victor over Heather Watson in the first match on the Hisense Arena, setting up a clash with the winner of Ana Ivanovic and Jelena Jankovic.
In her on-court interview after the match, she said: "I'm extremely happy to be playing my best tennis from the beginning of the season.
"Hopefully I can reach the same level for the rest of the tournament."
Radwanska is searching for her first Grand Slam title.
