Initially announced several months ago, UEFA have confirmed that the inaugural Nations League will take place in 2018, with the official seedings revealed today and the draw scheduled for January (because you can never have too many draw ceremonies).
So basically, there are four leagues - A, B, C and D - in which sides have been placed according to their position in the Uefa National Team Coefficient Rankings following the end of the European Qualifiers for the 2018 FIFA World Cup (play-off results will not be included).
Joining England in the top division are France, Germany, Spain, Portugal, Belgium, Switzerland, Italy, Poland, Iceland, Croatia and the Netherlands.
The UEFA Nations League group games, all teams will play each other home and away, will be held over six matchdays, during the "double-headers" in September, October and November 2018.
Euro 2020 will not only be the first contested over 13 different host cities as part of Michel Platini's grand plan for a celebration of 60 years of the European Championships right across the continent, it will also be the first major finals to feature deliberately what UEFA describes as "middle-ranking and smaller nations" as well as the game's elite.
Four group winners from division "A" in June 2019 will determine the victor of the first draw of the League of Nations.
Austria, Russia, Slovakia, Sweden, Ukraine, Bosnia and Herzegovina, Denmark, Czech Republic and Turkey complete the 12 teams. Division "B" will be divided into four groups of three teams.
The third pot consists of Montenegro, Israel, Bulgaria and Finland, while the final pot has just three sides - Cyprus, Estonia and Lithuania.
There are four tiers and nations have been placed with teams of similar ability. However, if a whole league does not have enough teams for a play-off, which is conceivable in League A, then the places will be filled by the best-ranked teams from the league below.
The top team in each group will be promoted and the bottom team relegated for the next Nations League competition which takes place in 2021.
Teams will be drawn into four groups of four.
League D: Azerbaijan, Macedonia, Belarus, Georgia, Armenia, Latvia, Faroe Islands, Luxembourg, Kazakhstan, Moldova, Liechtenstein, Malta, Andorra, Kosovo, San Marino, Gibraltar.
Euro 2020 qualification will begin after the group stages of the Nations League concludes and will run throughout 2019, with the play-offs taking place the following Spring.
But, for fairness, any team that wins their Nations League group will not be "promoted" into a play-off in a league above their own.
