In what has come as a huge shock to the sporting world, woman's tennis no.1 Justine Henin has retired from all tennis - effective immediately - with fatigue and a lack of drive being cited as the major factors.

At only 25 years old, Henin has won 7 major championships, and has had 10 tour wins in the last year.

Henin's career, while short, has been quite remarkable - and she becomes the first woman in Tennis history to retire while still holding the no. 1 spot.

Henin's small stature has meant she's had to overcome much bigger and stronger opponents - think 'Williams' - a testament to how truely gifted she has been, and still is, as a tennis player.

Good luck with moving foward, Justine - you leave behind a legacy that won't be forgotten.
