UEFA has stated that qualification for its club competitions next season must be done on "sporting merit", while reaffirming its belief that the 2019-20 season should be played to a complete finish where possible.
The football season has been postponed across the majority of Europe due to the coronavirus outbreak, with the Champions League and Europa League on hold and all major domestic leagues being suspended, or in some cases, abandoned.
The Belgian Pro League was the first to be called off early, while Scottish lower league clubs recently voted to end their seasons and the Dutch Eredivisie is set to be abandoned after all football in the country was banned until September 1.
The UEFA executive committee met in a video conference on Thursday to discuss how the league seasons could be ended, and also how qualification for the 2020-21 Champions League and Europa League could be decided.
This increases the possibility of leagues resuming behind closed doors, with the German Bundesliga announcing on Thursday that it is ready to resume play on May 9, pending government approval.
However other European nations, including England, Italy and Spain, have been harder hit by coronavirus, meaning even playing to empty stadia may be impossible - in which case UEFA has said participants in next season's continental competitions should be chosen based on their form this season, rather than reputation or riches.
UEFA also said it reserves the right to refuse admission to any club for next year's continental competition if it feels they have been chosen unfairly, including if "there is a public perception of unfairness in the qualification of the club."
Among the other discussions at Thursday's meeting, UEFA said it is still discussing how to complete this year's Champions League and Europa League, which were both halted part way through their round-of-16 stages.
It said it is considering whether to run the cups alongside leagues as it usually does, or wait until domestic competitions are done and play out the continental matches in August.
