Explanation of the behaviour Deviant behaviour is a type of negative instinct violating an informal norm in less offensive than a voluntary violation of a formal norm. Zinedine Zidane one of the most decorated players in the history of world football had a terrifying moment on such a night which was supposed to be his best night in his career. He was the skipper of the French team; they looked a formidable team throughout the tournament defeating big teams like Brazil, Spain and Portugal. Zidane was on the verge of adding his second World Cup feat in three tournaments to further glorify his career but had to defeat a very strong Italian side in the final to lift the world cup trophy. The evenly contested match was round off after the regulation time 1-1. Zidane scored for the French side with an audacious penalty and the equaliser was scored by Materazzi himself. During the second period of the extra time he head butted Italian Defender Marco Materazzi and was straight away given marching orders from Argentine match official Horacio Elizondo (Gneezy & Imas, 2014). After that incident Italy lifted the world cup trophy for the fourth time in their history.
