We know that UEFA has postponed the Champions League and Europa League finals without a date, but we do not know when competitions will resume in each country, postponed 'sine die' at the expense of the evolution of the coronavirus pandemic. Only the Belarusian league is being played and with an audience, albeit with limitations.
The return of the round of 16 from Manchester City-Real Madrid, Juventus-Lyon, Bayern Munich-Chelsea and Barcelona-Naples is yet to be disputed in the current edition of the Champions League. Atlético de Madrid, PSG, Leipzig and Atalanta are already in quarters. UEFA works together with national football organizations to reschedule the calendars and the intention is to play again, although, in most cases, there are no dates on the horizon yet.
The outcome of the 2019-20 Champions League is unknown, but of the 2020-21 edition if it is known, for example, that all the countries will again have the same participants by their coefficient, except Croatia, which wins a team to the detriment of Switzerland. Spain, England, Germany and Italy would have, again, four fixed teams. In addition to these 16 teams, The first two classified in the French and Russian leagues and the first in the Belgian, Portuguese, Turkish and Ukrainian leagues would have their place secured. In total 24 teams. The other eight to complete the 32 of the group stage would come out of the previous rounds in which 55 clubs will enter. Namely: the third classified in the French and Russian leagues, the second in the Belgian, Portuguese, Turkish and Ukrainian leagues; the first two in the Dutch, Austrian, Czech, Greek and Croatian league; Y the 39 champions of the countries to which they correspond one place per coefficient. Liechtenstein is the only country to be left without a participant again.
Let's imagine that everything ends as it is in the different European leagues. It is utopian, but it is one more scenario. If that assumption were to occur, half of the 32 teams that started this season's Champions League group stage would repeat: Real Madrid, Barcelona, Liverpool, Manchester City, Chelsea, PSG, Bayern Munich, Borussia Dortmund, Leipzig, Juventus, Inter Milan, Atalanta, Shakhtar Donetsk, Zenit, Lokomotiv Moscow and Bruges. They would have to regain their place in the group stage Olympiacos, Red Star, Dinamo Zagreb, Salzburg, Slavia Prague, Benfica and Ajax. And they would enter right now, if the different leagues did not compete again, Sevilla, Real Sociedad, Leicester, Borussia de Mönchengladbach, Lazio, Olympique de Marseille, Porto and Trabzonspor.
For example, Atlético de Madrid would be left out right now, leaving the champion Liverpool in the ditch in the last 16. It so happens that if the Cholo Simeone team won the Champions League, when it resumes, and was left out of the top four of LaLiga Santander, as it is today, Spain would increase its participants in the group stage in a team the next edition. The same case would occur with Napoli and Lyon if they eliminated, respectively, Barcelona and Juventus. Both, before the postponement due to the coronavirus pandemic, were out of the Champions positions and yet they are alive in this edition of the Champions. In addition, Tottenham de Mourinho, Valencia, the great Turkish champion Galatasaray or Leverkusen, in addition to Genk and Lille, are also out of the places that would give access to the next Champions League.
