Disliking a player doesn't necessarily mean you dislike his tennis. Maybe she's talking about his personality or his behaviour. Don't jump to conclusions.
For instance, I find Stepanek's game very attractive to watch, but recently he has done things that make me dislike him. Him, not his tennis.
And viceversa, I like Karlovic very much, he's really funny and witty. But I can't stand his game.
