I think we’ll see players returning to training with their clubs in mid May, possibly like Germany in small groups with no tackling. I think the PL will start matches behind closed doors in mid to late June with 2 games a week so the season is finished before August.
I think all league will try to finish the season on June and Jully. Of course behind closed doors. August will be reserved for European competition, CL and UEFA League.
Also, it is very possible we won't see open doors until the end of the year.
