Uefa has told its 55 member national associations that any plans to restart their leagues must be in place by 25th May.
European Leagues Deadline: The date of any resumption of leagues, and their formats must be communicated by that set date.
The guidance was issued by Uefa president Aleksander Ceferin, and general secretary Theodore Theodoridis.
Any national association, such as the Dutch Eredivisie, who has cancelled its season, will have to explain why.
The time limit for such an explanation will also be on the 25 May.
Deadline for European Competition on 27 May
The 27 May is the next date when Uefa’s Executive Committee will meet for a conference call.
The aim is to come to a conclusion, on whether the Champions League and the Europa League can be completed.
In a meeting last week, Uefa urged all national associations to complete their domestic calendar.
This would enable qualification into European competition for next season to be based on “sporting merit”.
Only government legislations or football related economic problems, are permitted by Uefa as legitimate reasons to cancel a season.
