Nadal or Djokovic still have chances to become the greatest player of this decade (beginning 2010 or whatever). There is no guarantee that there will be other truly dominant forces in tennis for the rest of it, and it isn't like the current younger generations are exactly proving themselves to be future all conquering tyrants. Currently for this period, Nadal has 5 Majors and Djokovic has 4. Greatest players of decades seems to be a popular point of discussion here (for no particularly good reason). Given the poor state of logic and meaning in such a list, I would like to further accentuate the pointless and arbitrary premise by venturing into discussions on whether Nadal and Djokovic could indeed become the 'player of the current decade beginning from X'. It would be quite an achievement according to flawed human logic, as though a decade beginning from 0-1 constitutes a macro season. Cheers, now please discuss!
