General Hercules, when the only consistent competition to Djokovic is almost 35, playing as many matches as the Serb.
I'm not sure what's going on with the rest of the players.
Right now, Murray and Nadal should be the ones barking at Novak's front door.
Now, they have trouble finding his house.
Andy: Which one might he be in Rafa?
Rafa: I don't know Andy, I was fishing with Uncle Toni. Maybe I'd look on top. Are you sure this is the right neighborhood?

Respectfully,
masterclass
ha ha ha. that was good general.
Rafa is out. could not even finish the match.
the heat was the culprit this time.
he just has no fitness. you cant win more than a match or two at a time with is fitness level.
you are spot on: andy and rafa should have been the ones to challenge Djokovic.
that falls on a 35 year old now. Roger is still out there working hard for his next slam. now that is the spirit.
he has it all and still he has the drive and the hunger for his next slam.
I would not bet against Roger at Wimbledon. he can get it done there.
