avan, he saw djokovic's name on the towel and yet he din't move from there.......that is very careless, rude, sore, bitter and awkward i am afraid to say.......
props, age is insignificant when he keeps moving like that and keeps producing tennis like that......fed is still in his peak, it's just that these days he has to deal with 3 to 4 players who can beat him on a given day.......personally i think 2010 and 2011 were his best years in terms of level of play.......he had better results in mid 00s because the field was clearly way weaker than today.......
