She was and still is one athlete in world of tennis of whom I always though is a 'cheater'. My only reasoning was pure logic - she is so small and light yet can pull out big guns and match girls 15cm higher and 20 kg heavier than she is like Serena, Kim, Maria, Ana etc.Anything is possible but I don't think Henin is the type to do that,in my opinion Henin while a great competitor has always been a little fragile emotionally and needs time off the grueling life of tennis to find herself so to speak,she may very well comeback in the future if she misses competing and tour,I hope she does.
At one point when she withdrew for a while from a tour, before that she looked beefed up and massive, after than she lost at least 20 pounds and came back to play. She quit with her coach then, whatever reason that was, at that point she was taking something.
Now this is only my opinion, and as I pointed out, pure logic is no proof for anything, let alone acusations of this kind. But I have a right to say whats on my mind on a public board, so I did.
