If you blame Azarenka, You need to blame Rafa as well
Seriously, stop the double standards. Nadal has started the whole fake injury fiasco and did it time after time against multiple opponents. Its how he won Wimbledon 2010, its how he won Hamburg 2008, FO11, etc.
The guy has used those tactics to his advantage many, many times. Since it was proved so succsesful other players have started embracing it and now we have a sport full of cheaters, both in ATP and WTA. Azarenka is just another cheater.
