is roger federer the greatest player to play tennis?

to say that roger federer is the best tennis player is very debatable,he is the best tennis player playing now yes he results that he having proves that,also i don t think that there are that realy great players around to test him,i don t think he the best clay court player in the world,my friend rafael nadel is clay,look at nadel results,it is a shame that rafael nadels body is starting to break down because he is the only player that can beat federeer at the big ocasions,i would have loved to see federeer play in the 1990s he would have not be so dominant,becker would have kicked his a,sampras would have kicked his BUT,agassi would have beaten him on some tennis court in the world in the tennis season,and to finish this off the reason why i bring up the 1990s is because that was the golden age of mens tennis,and i forgot to say the great stefan edberg,brill tennis player he would of beaten federer at some stage in the tennis season,wimbledon,usa open,,men tennis is rubbish because of federer he alsways wins and he kills the other male tennis players,i did nt even watch the australian open final 2010,or the last years wimbledon final because guess who always wins yes,BORINNNNNNNG
