I've seen Bartoli on several occasions, and I've never been overly impressed.
Yes, she's a useful player, she'll certainly make the top 30 at some stage in her career (as far as the word "certain" is certain) and has powerful groudstrokes, a fighting nature and times the ball well.
But double-handers from both sides can only reach the very elite in competitive tennis if they are formidable. Seles was formidable, Bartoli is not. Looking at them both, there is no comparison.
I saw her losing an epic against Sugiyama at last year's French, and she was a "definite" top ten player then. A year on, she hasn't really improved a great deal, in my opinion.
I'm sorry, but I'm far from convinced by this Bartoli girl.
