  1. Since the pots are not geographically distributed, which constraints will apply to the draw? Will be a limitation to 2 UEFA members per group? What about the other confederations?

    thanks

    1. Daniel, all known info about the draw is in this FIFA article.

    2. It looks like it is possible to have 7 of the groups with 2 UEFA teams each and 1 without any. But the more likely scenario is 6 groups with 2 UEFA teams and 2 with 1 UEFA team each.
      Other than that, they are sticking to the principle of having just 1 team from each confederation in a group.

      Delete
    3. Even if it is not specified in the earlier article I can see 6 groups with 2 eufa teams and 2 groups with one eufa team only being part of the final draw setup.

      Given the Pot 1, Pot 2 configurations Mexico are the only non South America or EUFA team in the first 2 pots so a non euro group would need Argentina/Mexico or Brazil/Mexico out of the first 2 pots. Pot 3 would then need to be CAF/Iran and Pot 4 CAF/Asia/NZ. If NZ fail to qualify it is defintely in no particular order ArgorBra/Mexico/CAF/Asia. This could be seen as unfair to Arg/Bra/Mexico over fellow South and North American teams so I don't think this will be allowed.

  2. Great analysis as ever. Although I am not convinced that Australia should be favoured to beat Honduras. I think the order of the legs is highly significant here with Australia having to make the long, long journey across many time zones to play the 1st leg in the highly intimidating environment of San Pedro Sula. They will do well to come away from here with just a 1 goal deficit, I think, all things considered. For the 2nd leg, Australia haven't exactly been convincing at home of late, and may have to win by a 2-goal margin to win, while Honduras will be happy to sit deep and counter.
    I don't see that Honduras are any weaker than Syria either and Australia struggled to get passed them.
    It should be a fascinating play-off but I think the odds are slightly in favour of the Central American team.

    1. Aussie fan here. We can't score. We have a very creative midfield who do generate chances but up front we have no true no 9.

      Also our coach thinks he is Bielsa reborn. He ain't.

      I'd say it's 50/50.

      Peru Nz is also interesting. Peru should beat Nz very comfortably but if things are tight after first leg Peru will get nervous. They want this so much only nerves can stop them.

    2. Yeah that is an interesting match-up too. Do you think the Kiwis will be quietly pleased that they didn't end up getting a more established nation like Chile, Colombia or even Argentina? It's perhaps not as cut-and-dried as people think.
      As an Aussie, I bet you are disappointed that the draw in 2015 didn't pitch Asia v Oceania in the play-offs. That would be 2 thunderous "derbies" for you, and far less travel for all players involved.

      Delete
    3. Mate as a football fan I'm annoyed about the play-offs. It's obvious it should just be stated Oceania vs Asia and nth vs Sth America. It should be set.

      But both Asia and nth America want nothing mg to do with the Sth American qualifier so we have these "draws" to keep Asia and nth America happy.

      It makes zero sense.

      As for Nz I've heard comments they feel they'll lose to any Sth American so they would have preferred argies and Messi to visit Nz. I'd give them a punchers chance. Not much, but a chance. :)

      Delete
    4. If the play-off draws fall "in sequence" then fate should throw Asia v Oceania together for the 2022 play-offs.
      Of course, it won't matter for 2026 onwards with that new mini play-off tournament.

      Delete
    5. Another Aussie here, the Honduras playoff will be a good test for both teams regardless of who starts as favourites I agree the first leg will be very important so hopefully my team finds it best form and can get a result our of that game.

      Delete
  3. I think you're underestimating Greece. Greece has never failed at a playoff, and when Mitroglou is playing the team can beat anyone.

    1. From a quick Wikipedia search it appears that Greece qualified through playoffs against Ukraine for 2010 and Romania for 2014 but none for the Euros. Whether the ELO model gives them a high % or not they should have some confidence with their recent history.

    2. Ed isn't biased. He simply run the numbers. In the end I agree Greece's chances are probably a bit higher, but Ed isn't underestimating anything.

  4. i hope Morocco will prove you wrong. Morocco is still first in their group and have at least 50/50 chance to go to Russia.

  5. Northern Ireland v Switzerland
    Croatia v Greece
    Denmark v Republic of Ireland
    Sweden v Italy

    Any smart guy willing to run some simulations? :)

  7. What do you think how the FIFA World Cup Final Draw will work? From pot 2 to pot 4 or they use Uefa Champions league method?

    ReplyDelete
  8. More reforms (or at least plans in that direction) announced by UEFA.

    Translation from Dutch:

    UEFA has plans for own World Cup

    UEFA is planning to organise it's own World Cup. The European football association confirmed this against press agency DPA after an article about this was published in German paper Bild Zeitung.
    According to Bild the plan of UEFA-president Ceferin is to organise a mini World Cup with 8 countries, every odd year. The qualifications could possibly already be scheduled for Autumn 2020. In 6 matchdays in the months September until November qualification matches should be played. The best 8 countries from the qualifications should play one year later a mini World Cup. UEFA confirms that these plans are a further development of the UEFA Nations League, a new European tournament with qualifications starting in Autumn 2018.

    With this plan UEFA seems to seek the confrontation with the FIFA, which organises the World Cup every four years. But according to UEFA the FIFA is informed from the beginning and is the relation between both associations 'very good'.
    According to Bild Ceferin has send his proposal already to all 55 UEFA member associations and they were interested, because a new tournament on global level would generate much more TV-money.

    1. There aren't any European teams in your Group E, and I don't think that will be possible in the actual draw.

      Delete
    2. @the reply above I agree that is logical as per my example on 14th October, who knows whether the boffins at FIFA will bother to consider the pros and cons.

      If so presumably Serbia moves to Group E with the Saudis moving to Group G and the Saudis moving to Group F for geographic reasons.

  14. Why not? There are no more than 2 European teams in same group as well as only one team from other confederations per group.

    1. From FIFA's material from today:

      "Each group must have at least one but no more than two European teams drawn into it."

  15. Just wondering - as the FIFA draw has its unique rules regarding teams from the same confederation, wouldn't it be possible to calculate probabilities for teams to be drawn together?

    For example, as Brazil can't have another South American team on its group, it has a 20% chance of getting Spain or England, right?

    Other interesting thing is Serbia - as the only European team in pot 4, they probably have a much higher probability of landing in Brazil or Argentina's group.

    It would be interesting to run a few thousand simulations of the draw and check if some interesting pattern arises.

    1. See here for the probabilities with drawing order pot 1 to 4 and max. 2 UEFA-teams in a group and max. 1 from other confederations. No constraint used here for at least 1 UEFA team in a group.
