According to the astrological projections (which are consistently correct) Djokovic won't win anymore slams this year.
Another one-slam year, no surprise.
The charts also indicated that the new generation (presumably this means Nishikori and Raonic) will rule in 2016.
And that is no surprise, considering Nishikori beat Djokovic at the US Open last year.
So Djokovic may be stuck on 8 slams for life (and that would mean Agassi is ahead of him in history, because Agassi has won the Career Grand Slam).
