Of course she won't worry
If she cares/worries about something, she should give some thoughts on how to improve things.
Till the end of 2007, Daniela is playing the same tennis. And the changes she did was totally the wrong ones. She just can't hit FH or BH with spins (from BS), she can't serve well, ball toss is terrible, movement is even bad, missing volleys, don't know how to hit smashes...
Anyway, it's the end of the year. All these stuff from Daniela, all these years.... make you feel disappointed and in general I can not have fun watching her matches... Not any more.
