World No. 2 Petra Kvitova admits that the amount of attention she received after winning Wimbledon affected her play. "I started to believe when I came home and everybody knows me on the street and I had many invitations and many interviews and everything,'' Kvitova told reporters in Sydney. “So then I knew life had changed, it was true, and it was a big [shock]. Now it's much better and now I know how I can live with this."
