Re: Beginning of the 2013
^I agree. A player that she has a negative head to head against can cause a lack of belief in herself to win even though she has the skills to do so.
We see how she plays against Azarenka, Kuznetsova, Cetkovska, Sharapova (improving greatly on this though) and Li Na (seems to be the new hurdle). She has beat all those players in the past but sometimes you just feel that she plays safer than normal when she faces them. She beat Li Na easily in Sydney just 2 weeks ago and Stuttgart but I think because it was on a slam stage she just played too safe.
But there will be plenty more opportunities. Once she is learning from her mistakes in the slams.
