I don't think I've ever heard of Vika badmouthing or complaining about another player, so in my eyes that makes her a little bit classier and more mature than Aga at this point. Bitching about another player when they're winning just makes you look bitter, regardless of whether you actually are or not.
Please, the only thing Aga criticized about Vika was her "doubtful" injury in Doha last year, earlier in the season she even had defended her when she talked about women's gruntings on court. Since that, she hasn't said anything about anyone. Her comments on the final were not disrespectful at all, but just maybe a little clumsy
After all, we all know that Li didn't have the same draw as Azarenka to reach the final, then it's just a matter of personal opinion.
Radwanska has always been talkative and critical, she says what she thinks generally without detour and sometimes she lacks of tact. I remember some years ago in Paris, she criticized the new WTA rules (in relation to the schedules) in front of a very embarrassed WTA representative, whereas most of the top players didn't dare to speak about it despite their disagreement. But that's also a quality, she can't be blamed for that and many people here show all they hypocrisy by criticizing her for what she says while they are constantly doing the same on TF.
Of course, many posters here seem to live for the drama. Well, there's not such a show in this case, and I'm pretty sure Vika's success has nothing to do with what Aga's thoughts, after all they also have a private life and some private stories, I guess. Some have already said it in this thread, but Aga seems to get on very well with players who have repeatedly defeated her on the court, and I really think she knows to make the difference between her private life and her tennis results. All the childish assumptions such as the 'envious' hypothesis remains assumptions without proof.
