If it's true that Justine Henin is to retire from tennis as reported in two Belgian newspapers earlier today (4pm update: it is) it will be a very sad loss to the sport. Having followed the game since I was about seven or eight, I can safely say that she is the most watchable player I have ever seen on court. Her backhand in particular is a thing of beauty.
She has been runner-up in two Wimbledon finals, in 2001 and 2006. If Ken Rosewall is by common consent the greatest men's player never to win the trophy, Henin will go down in my view as the finest woman player never to lift the crown.
