All these countries would have to get super lucky for there to even be a slim chance of any sport taking place for the rest of this year. This thing hasn't even got going properly yet (even in Spain and Italy) and the peak is a few months off. Then it will probably take at least the same amount of time it took to get going, to then slow down and get back to the odd case here and there. That takes us into next year.
If football (and other sports) don't shoot their load too early by voiding etc, they should just write off the 20/21 season's and continue the 19/20 season this time next year and rename it 19/21.
Obviously i hope they null and void the shlt out of it like.
