Almost 6m tuned in to watch Italy beat Spain 3-1 in their European Under-21 Championship opener on Sunday.
The match was already a sell-out at Bologna’s Dall’Ara stadium, and the Azzurrini attracted a 29.4 percent of the available audience – amounting to 5.6m viewers.
At its peak, a 30.75% share totalling 5,937,000 were watching Rai 1’s coverage of the game.
The figures exceed the 5.3m viewers and 28.79% share garnered by the senior team’s Euro 2020 qualifier against Greece earlier in June.
The FIGC said: “This data confirms the extraordinary popularity of Italian national teams for men and women in all competitions - the Euro U17, the Under-20 World Cup and the Women’s World Cup, in addition to the Euro Qualifiers and Under-21s - as evidence of a newfound attachment and of an ever-stronger identification on the part of the Italian fans with the Azzurri.”
