Gennaro Gattuso's father installed solar systems on the roof of his house. The Italian mafia called "Ndrangheta" did not like the move and demanded to receive a share of the deal.
The demand became violent and the mafia twice set fire to the car of the former player's sister. At this point the coach intervened, sending two people to pay the mafia 3,000 euros, and at the same time filed a complaint with the police. Several people were arrested on suspicion of extortion.
