Teams are separated into leagues - and then pots - depending on where they finished in last season's Nations League.
So England - in pot one of League A - will face a team from each of pot two, pot three and pot four in the top division. Wales, Scotland and Northern Ireland could end up in one League B group.
Timings
Right, just been given an update on the timings for the draw.
All being well...

Then C at 17:20.
Then B at 17:30..

Uefa increased the size of the top three tiers to 16 countries - meaning each group will have four teams - and decreased the size of the bottom tier to seven.
The teams who win each group in the top division - as England did last time - will go into the finals tournament in June 2021. The teams who finish bottom will be relegated to League B.
Unlike the previous campaign when everybody was qualifying for the Euro 2020 play-offs, only two World Cup play-off spots will be available for any of the 55 countries.
The best two Nations League group winners who do not qualify for the World Cup or play-offs through normal qualifying will go into the 12-team World Cup play-offs in March 2022.

What happened in the first Nations League?

The Nations League was split into four divisions based on countries' Uefa national team coefficients. Each country was drawn in a group of three or four teams, playing everyone home and away.
The winners of each of the top league's groups met in a finals tournament in 2019, which hosts Portugal won, beating the Netherlands 1-0. England finished third after beating Switzerland on penalties.
The team who finished top of each group in every division were guaranteed a Euro 2020 play-off place.

Yes I know, another Nations League already.
But you have to say they are better than international friendlies.
Thumbs up for those in agreement, thumbs down for those who disagree.
We go again
On a balmy day in June last summer, Cristiano Ronaldo lifted the trophy as Portugal claimed the inaugural Nations League tournament.
Just 268 days later, we look ahead to the next edition, heading to Amsterdam for this season's draw.
