Off or on the pitch? On the pitch he seems very reserved on his emotions, but don't know nothing about him being arrogant. Anyway, I don't think that there was an another player that had a comparable technique to him, not even the great Sampras. For that I liked him in the same way I liked the likes of Jordan, Ali or Messi.I know a lot of people who don't like Federer. He's insanely arrogant, so it's hardly a surprise.
