Re: Novak Djokovic: "I think the courts are a little bit slower"
The general trend has been a year on year decrease in speed everywhere it seems.
I feel it is going too far these days.
The current greatness league of active players in order of achievements to date (a factual comparison rather than fan biased assessment):
Federer 17 GS, 6 Year End Masters, 24 Master Series.
Nadal 14 GS, 27 Master Series, 1 Olympic Gold.
Djokovic 9 GS, 4 Year End Masters, 24 Master Series.
