And then they say she should retire. Why should she always be at her 20 something performance? She is clearly still very useful for top clubs and if she wants she can play in lower ranked teams too if she is useful to them and she wants to. People forget pro sports are a job and lifestyle too 
Congrats to VB for making the semis 
And also I think people forget that certain players can have certain roles in a team.. if she once was the best player on her team, it doesn’t mean she’s signed to be that same player 8 years after. She’s there to bring confidence, experience, reception stability etc etc.. and people expect her to be 100% every match, every set
