There is something called as ATP silent ban and they did that for Agassi and the 7 month injury break nadal after the Wimbledon, some analysts feel that it could be a silent ban sighting many reasons. nadal is a money machine for the ATP so even if they found him doping they wont ban him publicly. Hitting top spin and moonballing is different, everyone hits top spin and everyone moonballs but nadal uses that loopy moon ball over and over again to the opponents back hand specially if it is a one handed back hand, he just hangs in there until the opponent makes an error, its like slowing down the game play and get the opponent frustrated, he never plays an attacking all-round game attacking all aspects of the opponents play, if he did that to federer he would not have won one set of federer. Every player is aware of the moonballing but when they attack nadal's moon balling then he comes up with the MTO, more time wasting, more coaching and what not to spoil the rhythm of the player, that is was happened in 2014 AO final. Almost 70% of federer and nadal matches are on clay, clay is super slow, helps moonballing so it is not suitable for federer's game, he defeated roger in the 2008 Wimbledon after receiving time violation warning in the game and roger as every one knows was suffering from mononucleosis since the middle of 2008, the same disease which ended the career of robin soderling, so saying that he should have retired along ago when he has been consistently reaching the semi finals of AO year after year since 2003 is funny talk and pointless. Roger won the winbledon in 2012 beating Djokovic and Murray, he was 30 at that time so when you saying federer sucks means you probably did not understand the game that deeply or may be you have started watching the game only after era of the baseline bashers started. I used to be a big sampras fan and when roger defeated sampras i hated him for defeating my favorite player, in 2008 when nadal defeated roger in wimbledon i was the happiest guy ever, but then after that i started to get bored of nadal's play and behavior on court so i started to watch all of federer's old matches and wanted to why he is so great and i guess that is when i understood what an incredibly talent player roger was and how nadal did not even have 10% variation in shot making. Actually i used to think how can this stick looking player be so great but federer's amazing game play and how he made his attack look like a sword fight simply made me change my mind.
