I hold a high level of optimism for the German FA and I am sure that they will do a fine job with maintaining order once/if domestic play resumes. The Bundesligas are one of the few leagues in the world where clubs and their fans maintain majority ownership of themselves and while this action may appear to be a cash-grab opportunity, it's less so of a money-driven venture and more of a stimulus to the morality of the people. The Bundesliga did a good job at the start of the pandemic by being one of the first leagues to play behind closed doors. And I'm sure that they'll assess potential cases and spread seriously and effectively. Also, I may be incorrect in this evaluation, but from what I understand, the Bundesliga also appears to have predominantly domestic players as the roster make-up of their clubs, so there's a reduced chance of spread in that regard.
I just pray UEFA stays in their fucking lane and don't try to resume UEL/UCL. It's their fault that there was an explosion of cases in Italy and Spain by keeping doors open prior to ending matches. Especially the UEL matchup between Atalanta and Valencia.
I think domestic leagues should cautiously resume, and I'm sure they will depending on how the situation in Germany pans out. But it may be too soon for international play.
