UEFA will meet on Wednesday to discuss the future of the Champions League.

Aleksander Ceferin, the president of European football's governing body, recently said that the season would be lost if it could not restart by June.

"UEFA has invited the general secretaries of its 55 members associations to a video conference on Wednesday 1 April at midday to share an update on the progress made by the two working groups that were created two weeks ago and to discuss options identified with regards to the potential rescheduling of matches," a UEFA statement said.

"The meeting will look at developments across all UEFA national team and club competitions, as well as discussing progress at FIFA and European level on matters such as player contracts and the transfer system."

The meeting will discuss the possibility of playing behind closed doors.

Both the Champions League and Europa League were suspended in the round of 16.

Bergamo mayor Giorgio Gori said he believes that the Champions League match between Atalanta and Valencia at the San Siro is partly responsible for the outbreak of COVID-19 in his region.

The match was attended by 44,000 fans.

"The match was a biological bomb," said Gori in a Facebook interview.

"At that time we did not know what was happening. The first patient in Italy was on February 23. If the virus was already circulating, the forty thousand fans who went to San Siro were infected.

"No one knew that the virus was already circulating among us."

A third of Valencia's team also tested positive for COVID-19 shortly after. 

Gori added that there other factors for the spread of the virus in northern Italy.

"The match didn't cause everything because the spark was really at the Alzano Lombardo hospital, as a patient with unrecognised pneumonia infected patients, doctors and nurses."

Marcos Llorente discussed Atletico Madrid's comeback win against Liverpool in the Champions League round of 16, saying that belief and faith were crucial to his side's success.

"We knew we were going to have our chances," he said.

"I remembered all my family, all those who have supported me at all times and all my teammates."

Llorente moved to Atleti from Real Madrid over the summer.

Llorente, who has yet to hold down a first-team place, said he is focused on training. 

"I always work to my maximum level to be ready and available for when the coach needs me, in whatever position. Work and effort always have a reward, our obligation is to train every day and give everything in those sessions so that when the opportunity comes we are prepared to take it."

UEFA could authorize one-legged knockout matches in order to complete this season's Champions League and Europa League campaigns.

There are still hopes to complete both tournaments in late June, featuring a mini-tournament played in Istanbul and Gdansk.

Two Europa League round of 16 ties have yet to start, and could be decided by a coin flip.

The quartefinals and semifinals of both competitions would be played over one match. 

Atalanta playmaker Papu Gomez said that playing the Champions League match between his side and Valencia at San Siro worsened the COVID-19 situation in Bergamo.

Northern Italy is one of the hardest hit regions of the virus. More than 40,000 supporters attended the match.

Atalanta chose to play the match at San Siro due to construction at their home stadium.

“At the start there was a lot of misinformation, we all took it lightly. We thought it was just another strain of flu and so we continued to lead a normal life. When the deaths started, we started to feel afraid. Someone [at San Siro] was infected. We’re all waiting to see if any of us show symptoms.

"Playing those games was terrible. There were no checks in Valencia, everything was relaxed. I think the situation in Bergamo today has something to do with the Champions League game at San Siro. There are 12,000 inhabitants here and 45,000 were at the stadium that day," said Gomez.

Gomez added that it's difficult to focus on football.

“We’ve made a whole city happy in the last four years, but what we’ve been experiencing lately is something terrible, which I still can’t understand.

“We’re the country with the most infections after China, it’s strange. The people of Bergamo should be happy right now, proud of what its team are doing, but instead we have to focus on something else and think about the families that are suffering.

“I’m with them, they’re strong people who aren’t giving up and this period will come to pass.”

UEFA has postponed the Champions League indefinitely due to COVID-19.

The final of the tournament was scheduled to be played on May 30th at the Ataturk Olympic Stadium in Istanbul.

"No decision has yet been made on rearranged dates," the UEFA statement said. "The working group, established last week as a result of the conference call among the stakeholders of European football, which was chaired by UEFA President, Aleksander Ceferin, will analyse the options available. The group has already begun its examination of the calendar. Announcements will be made in due course."

Twelve teams remain in the Champions League after only half of the round-of-16 ties could be completed. 

Atletico Madrid, Paris Saint-Germain, Atalanta and RB Leipzig have already advanced to the quarterfinals.

Valencia said that 35% of their backroom staff and players tested positive for COVID-19.

"Several further tests for the COVID-19 coronavirus amongst Valencia coaching staff and players have come back positive," said the club in a statement.

Ezequiel Garay and Eliaquim Mangala were among players who confirmed they had tested positive.

Valencia had traveled to Milan to play Atalanta in a Champions League match before sporting restrictions were placed in Italy.

"Despite the strict measures adopted by the club after their Champions League game ... these latest results show the exposure inherent to such matches has caused a positive test rate of around 35%," Valencia added.

"All cases are asymptomatic and those involved are currently isolated at home, receiving medical assessment and carrying out their scheduled training plan."

A shortened version of the Champions League semifinals and final could take place over two weekends in Istanbul, sources told ESPN.

Discussions over the fate of the Champions League and Europa League will take place on Tuesday.

With UEFA ready to delay the 2020 European Championships, a cleared summer schedule would give way to complete both the Champions League and Europa League.

If both competitions are able to resume, it is understood that the quarterfinals will happen over one leg. 

All Champions League and Europa League matches were postponed as a response to the coronavirus.

“This includes the remaining Champions League, round of 16 second leg matches scheduled on 17 and 18 March 2020; all Europa League, round of 16 second leg matches scheduled on 19 March 2020; all Youth League, quarter-final matches scheduled on 17 and 18 March 2020. Further decisions on when these matches take place will be communicated in due course," released UEFA in a statement.

Draws for the Champions League and Europa League were also postponed.

UEFA will meet on Tuesday to discuss its next steps. 

The second leg of Champions League matches between Manchester City and Real Madrid, and Juventus and Lyon, were postponed due to coronavirus fears.

Real Madrid players were in quarantine after a basketball player tested positive for coronavirus.

Juventus defender Daniele Rugani also tested positive for coronavirus. 

Next Wednesday's matches between Barcelona and Napoli, and Bayern Munich and Chelsea, are set to go on as scheduled.
