We take a look at the odds for the 23 teams who have already sealed their place at Russia 2018.
No permutations or play-offs to worry about for the hosts as they prepare to welcome the world to their backyard next summer.
Five-time winners were the first to qualify, continuing their unique run of having been involved in every World Cup finals.
A run of 12 successive clean sheets for Carlos Queiroz’s men was only ended after their qualification had already been confirmed.
Delivered qualification by beating Australia 2-0 when Leicester’s Shinji Okazaki, Borussia Dortmund’s Shinji Kagawa and ex-AC Milan midfielder Keisuke Honda were all left out.
Led the way in the CONCACAF preliminaries and could start planning for Russia with three games to spare.
Roberto Martinez’s side were the first from Europe to guarantee top spot in their group and their golden generation – featuring a host of Premier League stars – will be fancied to do well next summer.
Heading for their ninth consecutive World Cup and, of those who have already qualified, only Brazil, Germany, Argentina and Spain have made it to more in succession.
A superior goal difference of +7 to Australia’s +5 meant the Saudis advanced and the Socceroos were left with two play-offs to negotiate.
Reigning champions and joint favourites were the only country to go through qualifying with a 100 per cent record and their goal difference from 10 qualifiers was +39.
For all their major tournament failures, the Three Lions are usually convincing during the preliminaries and so it proved again after a kind group draw pitted them with the likes of Slovakia, Scotland and Slovenia.
Managed to make it through despite being paired with Italy and the 2010 winners will have a point to prove after a disappointing campaign in Brazil.
Arsenal’s Alex Iwobi got the winner against Zambia as the Super Eagles became the first nation from Africa to punch their ticket.
Secured their spot with one game to spare thanks to a late strike from Kendall Waston earning them a draw against Honduras.
No player has scored more than Robert Lewandowski’s 16 goals in qualifying – a big reason why the Poles topped their group. The presence of Lewandowski and the fact Poland will be among the top seeds in Russia means they could be a lively dark horse at a big price.

Euro 2016 winners ended Switzerland’s 100 per cent qualification record with a 2-0 success on Tuesday that ensured Cristiano Ronaldo will be in Russia as the 20/1 shots bid for the Euro-World Cup double.
Would have taken a remarkable series of results on Tuesday for the two-time champions to miss out and Luis Suarez scored twice as they beat Bolivia to secure second spot behind Brazil in CONMEBOL qualifying.
Facing the possibility of elimination, Lionel Messi rose to the challenge with a hat-trick against Ecuador and Peru’s draw with Colombia and Chile’s defeat to Brazil sent Argentina through.
Snatched the last available spot for South American nations with a 1-1 draw against Peru, though had Chile drawn with or beaten Brazil it would not have been enough.
A debut World Cup finals appearance for Panama was confirmed with victory over Costa Rica and the United States’ loss to Trinidad and Tobago
