UEFA has sent a joint letter to their member leagues saying it was of "paramount importance" that domestic competitions be decided on the field and that canceling them should "really be the last resort."
The Belgian league abandoned the season and proclaimed Club Brugge as champions.
The letter sent Thursday said the working groups were "focusing on scenarios encompassing the months of July and August, including the possibility that the UEFA competitions restart after the completion of domestic leagues."
It also called on leagues around Europe to work together.
"Only an extraordinary coordinated effort of all competition organisers can help European football out of the crisis, recovering in full its core asset, the competitions," it said.
