Former world No.1 Justine Henin says she has matured during her 20-month break from tennis and can be a better player when she makes a return to the sport next week.

Henin, 27, told a news conference in Brisbane yesterday she "grew up" during her absence from the court and can eclipse the standard she set in winning seven grand slam titles. The Belgian will play in next week's Brisbane International and the subsequent Sydney International before contesting the January 18-31 Australian Open as a wildcard.

While keeping expectations in check, she said a second Australian Open title was "possible."

"I believe I can be a better player, I believe I can use my experience more than in the past," Henin said. "When you are into (playing tennis at) 200 percent you have no time to realize it. You are too involved all the time and all this time off helped me to realize everything I achieved."

Henin said her absence from tennis has given her personal insight and perspective, adding that she didn't watch a set of tennis in the first 12 months after retirement and now returns to the sport refreshed and self-aware.

"What I can say is I know myself much better and that's the most important thing," she said, appearing more relaxed yesterday than in the past, when she was often perceived as aloof.

"I'm 27 now. I just want to live my second career differently to how I did in the past," she said. "It's been a great experience to go out of the tennis world for 18 months and to come back because I feel I grew up."
