Described by all-time great Billie Jean King as "pound for pound, the best tennis player of her generation", Justine Henin managed a total of seven Grand Slam singles titles in a professional career that lasted just eight years.

Justine Henin made the surprising decision to retire in May 2008 aged just 25 years old, but with all that she achieved in the game, she certainly will not be forgotten in a hurry.

The Belgian won 41 career singles titles and more than US $19 million in prize money in her career. With four French Open titles, two US Opens and one Australian Open, she made the early 21st century her own with a series of dominant displays against some of the world's top players with a mixture of grace, power and toughness that was unmatched.

Despite reaching the Wimbledon final in 2001, Justine Henin did not win her first Grand Slam until 2003. She defeated fellow Belgian Kim Clijsters in the final at Roland Garros to become the first Grand Slam winner from Belgium and then defeated Clijsters again in the US Open final as she finished the year number one in the world.

After a long lay-off with a virus in 2004, Henin still managed to win Olympic gold before getting back to her best the following year, when she defeated Mary Pierce in straight sets to clinch a second French Open.

In 2006 she picked up her third title at Roland Garros with a straight-sets victory over Svetlana Kuznetsova, managing to go the entire tournament without losing a set.

A fourth French Open title followed in 2007 and a second US Open singles crown came soon after. These were to be the crowning glories of a fantastic career as Justine Henin retired from the game the next year after being named 2007's WTA Player of the Year.
