Due to the increasingly serious epidemic in Italy, the port derby of Sampdoria and Genoa could only be played empty, but strangely, during the course of the game, several burning smoke bombs floated in the sky, one of which was not biased. Buyi just fell on the court, and the others fell to the roof of the court. The referee immediately stopped the game and waited for the staff to deal with the interference factors before restarting. These smoke bombs are tied to small parachutes. It is visually observed that some fans deliberately threw props at the Ferraris Stadium in order to enhance the atmosphere of the Derby. This episode did not affect the progress of the game too much, and the two teams shook hands 1-1 in the end.
