Henin won ten tournaments last year including the French Open and the US Open and finished the year with
a WTA Tour best record of 63-4. But this year the Belgian lost three of her last seven matches while struggling with injury.
"It's the end of a wonderful adventure but it's something I have been thinking about for a long time," Henin told a news conference. "I
am leaving as the world number one and that is important and it is always better to go out at the top."
"I have been driving my career
based on an emotion but I didn't feel that emotion anymore since (2007) Madrid. At Madrid I felt I had reached the climax of my career. I
had thought about taking a break, but in the end I didn't think this was the right decision."
"I decided on returning from (last week's tournament in) Berlin to stop now."
Henin won 41 titles since turning professional in 1999 but today has retired for various personal reasons. She took gold in 2004 at the
Summer Olympic Games and was known for her mental toughness and for her aggressive and very beautiful, rare one-handed backhand and finesse game.
"I leave without any regrets and I know it is the right decision."
