They are not focusing on tennis like they should and it reffers especially to Radwanska (see Fibak's comments). Looks like she thinks she's already done her hard work and now she can enjoy the life on the tour. It is her decision but I think she still wants to achieve more than that. If she was such a type of hard-worker as Wozniacki is, she would probably be much better now as a tennis player. Friendships are important but I think they are harmful if it's between players during the tennis tournament, especially on the professional level.
Not that much as now. I just got to know her personality better throughout these years. There was a time I didn't like her but I sometimes wished her to win. I cheered for her during FC against Japan but year later I wanted Wickmayer to beat her in a tie against Belgium (cheered loudly for Domachowska though). But well, I didn't like her from the beginning.
