Quantifying the unfairness of the 2018 FIFA World Cup qualification

Abstract

This paper investigates the fairness of the 2018 FIFA World Cup qualifying competition via Monte Carlo simulations. The qualifying probabilities are calculated for 102 nations, all teams except for African and European countries. A method is proposed to quantify the degree of unfairness. Although the qualifications within four FIFA confederations are constructed fairly, serious differences are found between the continents: for instance, a South American team could have tripled its chances by playing in Asia. Choosing a fixed matchup in the inter-continental play-offs instead of the current random draw can reduce the unfairness of the competition. The move of Australia from the Oceanian to the Asian zone is shown to increase its probability of participating in the 2018 FIFA World Cup by about 65%. Our results provide important insights for the administrators on how to reallocate the qualifying berths.

Competitive Balance in the Post-2024 Champions League and the European Super League: A Simulation Study

“…Clubs' Elo ratings are supposed to capture the current playing strength of the teams. Therefore, it has been used for simulating match results in several previous papers (Cea et al, 2020;Csató, 2022aCsató, , 2022bCsató, , 2023aCsató, , 2023bLasek et al, 2016). In football, home-field advantage significantly increases the probability of winning.…”

Group draw with unknown qualified teams: A lesson from the 2022 FIFA World Cup draw

“…The same simulation model has been used recently to quantify the incentive incompatibility of the European Qualifiers for the 2022 FIFA World Cup 20 and the unfairness of the 2018 FIFA World Cup qualification. 27 The play-offs contain single-game matches, hence draws are not allowed. If the two teams score the same number of goals, the winner is chosen randomly.…”

Comparing physical, technical and tactical performances in the World Cup Qatar 2022

“…This competition is organized by FIFA and takes place every four years in a different part of the globe (Andersson et al, 2021), where the best teams from each continent try to win the title of world champion. Nowadays, there are six football confederations (Csató, 2023), each with a few specific places for participation. The South American Football Confederation (CONMEBOL) has three to four teams, 13 teams come from the Union of European Football Associations (UEFA), four or five from the Asian Football Confederation (AFC), five teams from the African Football Confederation ( CAF), three or four teams from the Football Confederation of North, Central America and the Caribbean (CONCACAF), and zero or one from the Football Confederation of Oceania (OFC), in addition to the host country that has a direct entry (Durán et al, 2017;Kessouri, 2023;Kubayi & Toriola, 2020).…”
