He behaves emotional in the playground because he has bulgarian blood anyway thanks for answer...
Sorry, but all others Bulgarian players that I know are rather quiet on court.
To me, Zlatanov is behaving much more like an Italian, always arguing with referees, sometimes being arrogant to others players, and so on.
The year before Zlatanov, that was Papi who got a yellow card in Tours, very much in the same circumstances, contesting a point he should not have when his team was in the lead, and igniting the audience in the process. And Treviso was eliminated exactly in the same way after having dominated the beginning of the game.
