UEFA Euro 2020 Qualifying Simulations - Draw Impact

As always, the group stage draw has winners and losers.
Clearly the group of life is group G, where all teams raised there chances of qualifying
Turkey is also a winner, and it actually the second highest ranked team in its group according to ELO (although Iceland still has higher chances of qualifying including the playoffs).
Northern Ireland decreased their chances the most by drawing Germany from Pot 2.
Group F is the group of death, with 4 teams capable of qualifying and all teams lowering their chances of qualifying.

The simulations are based on World Football Elo Ratings and are done by Poisson simulation system described here: Football Club Elo Ratings.

Summary by group:

Group Difference
A 12.56%
B -9.48%
C -15.12%
D -11.83%
E -8.50%
F -28.87%
G 35.85%

UEFA Euro 2020 Qualifying Simulations - Post Nations League GS

After UEFA Nations League 2018 group stage is over, it's time to look forward to UEFA Euro 2020 main qualifying.
The simulations are based on World Football Elo Ratings and are done by Poisson simulation system described here: Football Club Elo Ratings.
The biggest winner since the previous simulations is Norway, who managed not only to win its group, but also finish with the second best record of all Group C teams, and then guaranteed playing at home at the playoffs if it wont qualify directly.
The biggest loser is Iceland, who did not manage to make a surprise at both FIFA World Cup 2020 and UEFA Nations League 2018 GS., including some heavy defeats.

Here are the results for 100K simulations:

UEFA Euro Qualifying - Nations League Impact

Hello,

Today I will make an analysis of the impact of the new change in UEFA Euro Qualifing System, in which 4 teams would qualify from the Nations League Playoffs.
I included in the analysis the following scenarios:

  1. The real system of UEFA Euro 2020 Qualifing
  2. A scenario for each team where it is assigned to one league above (lowest pot) 
  3. A scenario for each team where it is assigned to one league below (highest pot) 
  4. A system in which there are 8 group of 7-8 teams, where top 3 teams in each group qualify.
  5. A system in which there are 9 group of 6-7 teams, where top 2 teams + 3 best 3rd placed teams in each group qualify, and the other 3rd place teams go to playoffs (previous system).
  6. A system in which there are 11 group of 5 teams, where top 2 teams + 2 best 3rd placed teams in each group qualify.
The most interesting finding is that being in League A actually improves the chances of a team to qualify to Euro 2020 comparing to group B, and being in League B improves the chances of a team to qualify comparing to League C. It has two reasons:

  1. In 99.8% of the simulations, at least 8 League A teams qualified through the main qualifing, making all league A teams qualify at least for the playoffs. For League B, in 87% of the simulation all teams qualifies at least for the playoffs.
  2. The main qualifying seeding is based on the Nations League final standing, and higher league means higher seeding.

All scenarios are done with one million simulations of the draw and the matches (Elo ratings as of 1.12.2017).
