Seven Grand Slams at 25 - how many more titles would Justine Henin have won?

I don't think anyone could believe the news last week that Justine Henin has retired from professional tennis. I mean, if it had been news of Amelie Mauresmo retiring then this would have been more plausible after the former world No.1 had dropped down the rankings and was struggling to win matches, never mind tournaments.

But Henin! The current world No.1 - and by a distance. What a sad day for  tennis as the diminutive Belgian finally hung up her tennis shoes.

Justine was one of the great women's players of recent times. I remember when she first burst onto the tour in 1999, winning her debut tournament in Antwerp as a wildcard. I instantly took notice of the name as its very rare a player has the confidence Henin had right from the start of her career.

he never looked back and went on to win 41 singles titles throughout her glittering career.  Her seven Grand Slam titles puts her right up there with the very best players, and you have to remember she retired at the age of just 25. How many more Grand Slam victories could she have had? I would say at least another four or five; if she had played into her early 30s, maybe more.
