Jo-Wilfried Tsonga has admitted that he must produce his best form consistently to have a chance of making the latter stages of this year's Australian Open.
The Frenchman has made the final before in Melbourne and believes that he has enough quality to mount a title challenge.
He told reporters after his second-round win: "It's so hot that it was tough to control the ball. I'm an aggressive player so once I got used to it I recovered.
"I had some trouble in the second set but I kept fighting and used my movement to get the win.
"My preparation has been a little better coming into this season and I have an excellent chance in this tournament but I know I need to play better to trouble the top players."
