She was playing just the way she was when she retired. Her footwork, her movement, the back-hands, the volleying, the drop-shots were all there. Not an inch less. But I guess its the same problem that has started to haunt her again i.e she gets into a shell when her opponent starts over-powering her. She becomes incapable of breaking the rhythm but instead she starts feeding her opponent with even juicier short ones. This is something that she has to work on if she's dreaming of becoming world no.1 again.
