The Italian Federation and Government reportedly have until April 7 to guarantee crowds at the Euro 2020 games in Rome or lose the hosting rights.
The tournament was postponed from last summer due to the COVID pandemic and rescheduled in the same arenas starting from June 11 with Italy against Turkey at the Stadio Olimpico.
This is an itinerant competition, so there will be several host countries and cities all over Europe.
UEFA have warned they will not allow games to be played behind closed doors, so if a city cannot guarantee fans will be allowed in, the venues could change.
There are growing fears in Italy that the Government and FIGC will not manage to give the all-clear in time, so Rome could see its fixtures removed.
The Stadio Olimpico is also due to host Italy-Switzerland on June 16, Italy-Wales on June 20 and one of the quarter-finals on July 3.
Above all, it is the venue for the opening Euro 2020 ceremony.
According to the latest reports, UEFA have set a deadline of April 7 to guarantee fans will be allowed into the Stadio Olimpico or find alternative venues.
