I wonder if she can lately. I am not taking away anything from Ksenia, perhaps she played a great match (I have not seen it), but observing Marta's results lately and her play just simply points out at mental issues. Marta definitely needs a trainer, but before anything she needs a good therapist that she trusts. Some coaches are good at it as well. I saw a few of her matches this year, technically some of them are not bad (and I mean NOT BAD), but her ability to stay concentrated on the game is not there. Marta falls apart for any reason, becasue she is winnning or she is losing. Seek help Marta if you want to achieve something; you are still young!
The best of luck to all tennis players; The game is on!
P.S.Well,... special luck to Agnieszka Radwanska, Marta Domachowska, Daniela Hantuchova, Urszula Radwanska
