The EURO 2020 group that is almost completely formed before the draw!

On Saturday 30th November the EURO 2020 draw will take place. It will be a special tournament, with 12 hosts, something as innovative as the draw that awaits us to in order to find out the composition of the six groups.
Out of the 24 countries that will play in the tournament between June and July 2020, 20 have already qualified. The other teams will be decided in the playoffs in March.
The rarity of the format, and therefore of the draw, means that we already know three of the four countries that will make up one of the groups. Group B. But what's the reason?
Belgium are the top seed in the group, whereas Russia and Denmark have automatically been assigned to this group as Saint Petersburg and Copenhagen are the hosts.
