Re: Jelena Jankovic
I think she lacks motivation at this point, and to win a slam - or to do well on the tour in general you have to be passionate about it. Jelena at her peak didn't win a slam, but the sad thing for her is that she started to slip at the wrong time. The Jankovic of 2008 would have been a very serious candidate to win a slam in 2010-2011. So in a way, she possibly has missed her window of opportunity. Maybe she needs to take a break and only come back when she actually feels like playing again.
