Some European leagues could be cancelled admit UEFA
All 55 European national FAs met by video conference on Tuesday when ways to finish the season were outlined.
Each involved a June start, with the Champions League final on 29 August.
Earlier this month, Uefa warned leagues that ending competitions early could result in them forfeiting Champions League and Europa League places.
However, the uncertainty over when football can restart has made detailed planning impossible and for the first time, Uefa has accepted completing the season in some countries may not be possible.
“There was a strong recommendation given to finish domestic top division and cup competitions, but some special cases will be heard once guidelines concerning participation to European competitions – in case of a cancelled league – have been developed,” Uefa said in a statement after the meeting.
It was not explicitly outlined to associations what “special cases” would mean. However, Uefa expects leagues to come to it with their reasons for wanting a season to be ended prematurely.
The Belgian Pro League became the first major European league to be cancelled on 15 April.
Uefa has to work out the qualification process for its 2020-21 competitions, which might overlap with the end of the 2019-20 season.
It is also not clear how Uefa intends to play out the Champions League and Europa League this season, with both still to complete the last-16 stage.
