Plans for this summer's European Championships hit a massive roadblock on Monday evening when it was announced the whole of Italy had been placed in lockdown.
By Tuesday night there were reports in Italy that several European federations had asked Uefa to postpone Euro 2020 in order for suspended domestic competitions to be completed.
Uefa moved swiftly to dismiss those claims, and yet, hours earlier Spanish football announced plans to hold top flight games behind closed doors for the next fortnight.
And then in the early hours of Wednesday the first Premier League game was cancelled due to coronavirus.
What makes the postponement of Man City v Arsenal more stark is that it was called off as a direct result of Arsenal playing in a European tournament played across different countries.
Doubts have now been cast of the Champions League being finished this season (especially with two Italian sides currently still in the competition).
And yet Euro 2020 kicks off in Rome - a city that you currently can't fly to - in 93 days.
That's also when the virus is meant to peak in the UK, according to Boris Johnson.
Amid the coronavirus pandemic, it now looks increasingly unlikely that the tournament will go ahead in its current format.
Here, we look at the current situation and what happens next.
Why Italy in particular has put the tournament in danger?
There have been 10,149 confirmed cases in Italy. There have been 631 deaths with 724 people having recovered from the illness.
The country is currently on lockdown given the severity of the situation with 60 million residents living under new measures which mean that no one can leave the country.
Residents are asked to stay at home and not to go out and socialise. All football matches have been cancelled and won't restart until at least April 3.
The New York Times report that gym subscriptions and prepaid cinema and concert tickets are now rendered void as 'non-essential socialising' is now forbidden.
Museums, cultural centers, swimming pools, spas, sports halls and ski resorts across the country are all also reportedly shut.
Restaurants, cafes and shops can operate only if customers stay three feet apart.
Italians can travel only on essential journeys, such as valid work-related reasons or family-related reasons, while it is reported that train travellers must sign police forms to state their reasons.
Cars are also being stopped for police checks.
Healthcare workers have to cancel their holidays to deal with the influx of coronavirus patients, too.
All mortgage repayments have, however, been suspended.
The UK government has advised against all but essential travel to Italy.
All this raises two questions.
How can Italy be ready to host Euro 2020?
By June how many other countries are forced into introducing similar restrictions on movement?
Italy Prime Minister Giuseppe Conte said: "We're having an important growth in infection... and of deaths.
"The whole of Italy will become a protected zone.
"We all must give something up for the good of Italy. We have to do it now."
Where does UEFA stand?
The tournament is spread across 12 different locations, a decision which was made to celebrate the 60th anniversary of the tournament.
It just so happens that this year is quite possibly the worst year they could have chosen to host it over so many countries and cities, not that they were to know that.
With so many of the countries partaking in the tournament having been hit in some shape or form by the coronavirus, only four of the 12 have not had any cases as yet, it would appear nigh-on impossible to contain the spread of the disease in such a tournament across so many different locations.
Having said that It's fair to say UEFA will be desperate for the lucrative tournament to go ahead.
But essentially individual governments hold the power - and due to the format of the competition, UEFA are having to deal with a few of them.
According to the Associated Press UEFA is asking governments across the continent to ensure the Championship goes ahead.
Based on advice received from the World Health Organization, UEFA believes a city can host Euro 2020 games if it has the medical infrastructure to treat COVID-19 patients while still providing the necessary facilities to cope with tens of thousands of fans.
The latest broadcast from UEFA, however, is that there is no change to the planned timetable of Euro 2020, which is set to take place between June 12 and July 12.
"Euro 2020 will kick off on 12th June 2020 in Rome," A UEFA statement to WalesOnline read.
"UEFA is in touch with the relevant international and local authorities regarding the coronavirus and its development.
"There is no need to change anything in the planned timetable. The issue will be kept under constant scrutiny."
However, it is understood that UEFA has been told by the WHO that it does not expect the virus to have been contained by the time Euro 2020 opens on June 12 in Rome.
By June the situation in Italy may have considerably improved, but by then the situation is likely to have worsened in other host countries.
The virus will hit its peak during the Euros
In this country, we have been told that the coronavirus is set to hit its peak in June , meaning the situation is almost certain to worsen.
The latest communication from EUFA executive committee member, Michele Uva, told Italian media outlet RAI: "We are at the waiting stage.
"We are monitoring country by country, and football must follow the orders of the individual countries.
"The sporting path will only be closed if the situation gets worse."
That seems to suggest that the organisers are ready to act should the spread of the disease worsen.
Given the sheer volume of sporting events having already been called off or suspended, and, remember, football have been arguably the most proactive sport in doing so, it appears highly likely the scheduled tournament will have to shift.
Should the virus hit its peak in June, who is to say whether or not the UK will have followed suit with Italy by then and be in lockdown barring essential travel?
With Wales set to play against Switzerland and Turkey in Baku as well as Italy in Rome, Welsh fans might not even be able to leave the country, should the UK government take extreme measures.
Football at a stop or being played in empty stadiums across Europe
UEFA said reports that European football federations had requested that the 24-team tournament is moved to next year were "completely untrue."
And yet there are certainly concerns across Europe over how and when suspended domestic competitions will be finished?
Without Euro 2020 it would make it a lot easier to extend Serie A or even the Champions League for example.
According to reports in Spain, the Champions League and Europa League may be suspended after the round-of-16 fixtures.
Some matches will already be played behind closed doors next week but UEFA may be forced to suspend both competitions before the quarter-finals.
All sport in Italy, including Italy's top flight Serie A, has of course been suspended.
It had already announced that all games were going to be played behind closed doors until April 3, however Prime Minister Giuseppe Conte has now confirmed all sport is suspended until at least that date.
Spain yesterday announced that the top two divisions will be played behind closed doors for at least the next two weeks.
And in France matches in Ligue 1 are to be played behind closed doors or in front of no more than 1,000 people.
Manchester City's Premier League match with Arsenal became the first in England to be postponed while Wednesday's Rhine derby between Borussia Monchengladbach and Cologne will be the first Bundesliga game to be played behind closed doors.
Wolves' Europa League last-16 first-leg match against Olympiacos will also be played behind closed doors and Ireland yesterday announced their international friendly with Slovakia, in Bratislava, on March 26 will be played behind closed doors.
Other major events are already off or in doubt
Formula One was one of the first sports to react to the outbreak, cancelling the Chinese Grand Prix, which was due to be held in Shanghai on April 19.
The Tokyo games could be moved until the end of the year if the outbreak worsens.
The Six Nations has of course been hit badly with three fixtures cancelled and tennis bosses cancelled the BNP Paribas Open in Indian Wells.
A decision is also expected to be made on whether the London Marathon can go ahead.
The contingency plans for Euro 2020
While WalesOnline has contacted UEFA to ask what contingency plans have been put in place, they, as yet, have not divulged those plans.
UEFA general secretary Theodore Theodoridis told the BBC, however, that the governing body had discussed what they would do if the virus worsened, but was reticent to reveal details.
"We have been working on different scenarios," he said.
"The Euros start in June. We have (qualifying) matches coming in the next weeks. We don't want to share further details.
"The more urgent matters are coming in the next two weeks. But there are plans for everything."
UEFA president Aleksander Ceferin said he is confident they have the right plans in place to deal with a number of issues, including the coronavirus, but what exactly are they?
It seems unlikely they would go ahead with such a big tournament in a behind-closed-doors capacity, especially given how important the fan factor is in such a tournament, not to mention the income lost by host nations and venues.
Would there be enough financial clout and logistical-planning time for them to streamline the tournament to be played in one country?
Brussels has already stripped of hosting Euro 2020 games because its stadium wasn't finished and additional games were placed at Wembley, which has the semifinals and final in North London.
Some think England could host the whole thing.
But it seems as though it would be a massive upheaval in a relatively short amount of time, meaning said country would have to already have the correct infrastructure in place, from football stadia to healthcare provisions, to deal with hosting a tournament of such a magnitude.
Pound said they could potentially relocate the Olympics in such a way and UEFA could well follow suit if that is the case.
A third option could be to follow what other sports have done so far and postpone the tournament.
Given the number of cases are likely to skyrocket before the tournament is set to begin, this, in all likelihood appears to be the most likely option.
UEFA have said they are in contact with all the governments staging the tournament, saying they will follow the advice of those in power in the affected countries.
What would changes mean for travelling fans?
Postponing a tournament, moving it or playing games behind closed doors would all, in all probability hit Wales fans in the pocket somehow.
UEFA would have to offer refunds for cancelled matchday tickets but accommodation and flights would be another matter.
If an event is moved and fans cannot make the rearranged date they should also be entitled to a full refund.
The Association of British Insurers confirmed this week that someone booking a holiday to, say, Baku in June, and buying travel insurance would be covered for cancellation of a holiday, but only if the Foreign & Commonwealth Office (FCO) later advised against travel to the country.
The insurance has to have been bought before a country was declared off limits.
However insurers could move the goalposts by arguing the virus was a known problem when the policy was bought. Fans should also check the small print of their travel insurance policy.
However, according to Money Saving Expert, if the tournament was cancelled but Baku - to use the same example - was not an off limit country at the time insurers might not pay out.
The website said: "We asked if customers could get accommodation and flight costs back if they booked a trip for a specific event (eg a football match), and it's cancelled but there's no FCO warning against travel. Every insurer bar Allianz told us you wouldn't be able to claim."
In terms of individual airlines passengers booked on to a flight that has been cancelled by the airline because it no longer wishes to operate the flight, are entitled to a full refund.
If flights have not been cancelled but the tournament has then it will depend on the airline you are travelling with.
Some airlines will offer free cancellations - meaning a full refund.
Some will charge you for cancelling - meaning you will get some money back.
And some will let you move your flights - if the tournament is put back to a later date (some will charge for this but many airlines are offering this service for free for those affected by coronavirus).

Anyone concerned they may have coronavirus is advised to visit an online COVID-19 symptom checker .
They are also advised not to attend their GP surgery, the hospital emergency department or the minor injury unit.
