“After everything that’s happened, now the situation is improving, I think the time has come to start providing fans with something to be satisfied about,” said Italy coach Roberto Mancini, who tested positive for Covid-19 in November but was asymptomatic.

The tournament was postponed last March when countries were scrambling to contain virus outbreaks and major sporting events around the world were cancelled or put on hold.

Many worry that it’s still not safe to bring tens of thousands of fans together in stadiums across Europe, but organisers hope measures including crowd limitations, staggered arrival times for fans, social distancing rules and lots of hand sanitiser will help prevent a resurgence of virus infections, which have dropped sharply in Europe in recent months.

In Rome, fans entering the stadium are required to bring documentation showing they have been vaccinated against the virus, tested negative in the 48 hours before the match or already had the disease.

“Let’s hope for the best,” said Alessandro Savelloni, a 36-year-old Roman having a beer with his wife at a street bar before the match. “We are coming out of a dark period. People need freedom. To return to normal life.”

The virus already has had an impact on the tournament, which for the first time is not being hosted by one or two nations but is spread out across the continent with matches in 11 cities.

Spain captain Sergio Busquets tested positive for Covid-19 and will miss the team’s first match against Sweden in Seville on Monday. Another Spain player tested positive, as did two of Sweden’s players. The Spanish squad was getting vaccinated Friday.

Russia winger Andrey Mostovoy then became the first player to be cut from a national team on Friday after testing positive.

Italy’s opening match brought together the biggest crowd in the country since it went into a full lockdown 15 months ago, even though the stadium was filled to only 25 per cent of its capacity.

Tenor Andrea Bocelli, who recovered from Covid-19 in 2020, delivered a powerful performance of Giacomo Puccini’s “Nessun Dorma” at the opening ceremony.

Bocelli touched the hearts of millions in Italy and beyond when he performed a solo concert at Milan’s empty cathedral during Easter last year. Milan is the capital of the Lombardy region, at the time the epicentre of the pandemic in Europe.

In Rome and elsewhere in Italy, most virus restrictions have now been lifted. A midnight curfew and a requirement to wear a mask outside one’s home are the most tangible ways in which the pandemic still affects the daily lives of citizens.

Shops, restaurants, gyms, museums and theatres have reopened. Roman traffic has returned to its usual chaotic state, with swarms of scooters competing for lane space with honking cars.

The tourists are coming back, too, though the historic centre with its famous landmarks remains less congested than what’s normal for this time of year.

Metin Karagulle, a Turkey supporter riding past the Colosseum on an electric scooter before the match, said that being in Rome for the tournament opener was an “unforgettable” moment.

Italy still bans non-essential travel from Turkey, but many Turkish fans living in other European countries have travelled to Rome to support their national team.

“I am hoping for a good day, a good show for the opening of the Euro,” Karagulle said. “Let the best win!”
