I don't dislike anything about my favourite players. It's a package, take it or leave it
I actually enjoy laughing at their flaws.
But, well, if I had to pretend I did NOT enjoy some of their flaws:
-Kafelnikov : he had a pretty bad temper, smashed lots of rackets... He was pretty weird in press conferences. And he's put on so much weight since he stopped playing.
-Coria : well, he also had a pretty bad temper, sometimes got into ridiculous arguments with the umpire, could be quite rude. He's also quite bad at spelling in his tweets, or maybe he can't be bothered. Of course he also inflicted me the biggest sports-related trauma in my entire life with that epic choke in the 2004 RG final.
-Ferrer : he does everything he can to make himself look uglier than he his on court (wears huge shirts, hunches his shoulders, gets his hair soaked even before walking onto the court and wears a rather unflattering headband - all very practical but not very stylish) - I am still mad at him for not having kept his long hair - Of course I don't like that he has problems beating the top 10 and especially Federer and Nadal on clay - He is sometimes too nice and does not stand up for himself.
But of course I actually like most of those flaws. I enjoyed laughing at Kafel or Guille's occasional bursts of bad temper, and I find it pretty cool that Ferru is somewhat an undercover handsome guy
