i've heard rumours that Rafa Nadal's parents are getting a divorce that's why there was a sudden drop with his match with soderling
I heard rumours that he had heard rumours about the divorce during the Hewitt match and was quite happy about it, hence his good performance. Then against Soderling the adrenalin rush of it all just wore off and he got bitch slapped.
I am unsure as to whether Nadal will be able to really pick himself back up after hearing of this news, I guess Wimbledon will tell us. As for his knees, well they just further compound this problem. If there is one man who can show the mental resilience though to come through this strong, it has to be Rafa.
