Djokovic can play on any speed with zero resistance in that era except Roger and Nadal on clay he would make every one............2003-2007 is probably the weakest era in the last 20 years.........Hell mugs like Nalbandian,Haas are hailed as supreme players just because they were the only one except Rafa to challenge Federer......Give me a break..........Also court speed was almost the same back then in reverse......Everything was fast.......AO,US Open,Wimbledon,Masters evens except clay?How is that fair?Please tell me
the courts in that time were not similars like today`s courts....
us open was much more faster and the same with australia and masters cup for example , even wimbledon was more fast befores that the organizers changed the original grass..
this era is strong????? always the same guys fighting for slams and in this era federer was the second more old nº1 in tennis history , that is strong????? or old players like ferrer in the best moment of his career?????
