1. What contrast is evident in the two cultures represented here?
The Italian coach is very vivacious, loquacious and emotional. He clearly contrasts dramatically with the more reserved and low-key character of the English. With two such different cultures, it is not surprising that misunderstandings can arise. Just as there are styles in verbal and non-verbal communication, there are also styles in conflict resolution. In England a "discussion" or "integrating" style is favored in which the reasons for conflict are addressed directly but emotions are restrained. Italians tend to use an emotionally expressive style.
2. What communication style is used by the coach, Paolo di Canio?
The Italian coach speaks fast and uses gestures. His face is quite expressive as well. In terms of communication style, it is direct and elaborate (highly expressive, even exaggerated language). He tends to raise his voice often and uses a lot of repetition. This is typical of a dynamic communication style which tends to treat conflicts as high drama. This is far removed from the customary English communication style, famous for its understatement and humor.
3. What is the conflict involving the coach?
As is often the case with sports coaches, di Canio has disagreements with the refereeing. In this particular case, he protested a call he thinks the referee missed and was ejected from the game. That was in part due to his leaving the "technical area" (coach's box) and being too demonstrative in his protest. Disagreeing is allowed in an English sports context but the disagreement needs to be expressed in a form consistent with English norms of behavior and communication. The fact that di Canio has been ejected repeatedly from games suggests his behavior and communication style are unacceptable from a British perspective.
4. To what extent is the conflict cultural?
The verbal style and body language used by di Canio are a large part of what causes the conflict. It's not just that he uses emblems (hand gestures) and illustrators (gestures accompanying speech), but as he puts "I talk with my body language sometimes". That includes, as seen in the clip, kicking one of his players in frustration. Such behavior is by no means limited to Italians, but in an English context, it is likely to be seen as beyond the pale.
5. Why is di Canio not going to change his behavior?
He says at the outset, "I have a culture and I don't stop my culture". His communication style is not something he is willing or able to change as it is part of his cultural identity that it is important for him to maintain. Di Canio has been a controversial figure in soccer going back to his player days. His "expressiveness" got him penalized multiple times as a player, as well as later as a coach. As a player in Italy he was also criticized for his tattoos (one in tribute to Mussolini) and his use of the Italian fascist salute.
