Private they have had their moments, Roger and Rafa, certainly.
Djok has had more than them, though, definitely.
And he doesn't get, that it's his attitude that is the reason he is not as well liked. Respect has to be earned- and both Fed and Rafa have earned that. A player like Delpo- is one of the most like men on tour, by players, spectators and officials alike.
He gets frustrated because he thinks just winning makes him special, and deserves automatic love and respect. It's not how it works.
I was shouted at on here for being mean to Serena- because hey, she's won 23 slams, you know. Doesn't mean she's not obnoxious though, does it? Margaret Court won 24- and look how she turned out.
It's why he imploded after he won the RG in 2016. He did it- the grand slam. And every one around him went 'meh'.
It messed with his head.
