Performance Variables

This study aims to determine the best player in each position from among the footballers who played in the 2018 World Cup in Russia. Player statistics for those who played over 200 minutes were obtained from the FIFA official and transfermarkt.com websites. Selected performance variables were then calculated per 100 minutes and the results were normalised. Kruskal Wallis H and Bonferroni Tests were used to determine the weights of the variables before the analysis. As the variables will have different values according to the players’ positions, the weights for each position were calculated separately. Finally, the performances of the players on the basis of the variables used were ranked for each position using the TOPSIS method. A second analysis was undertaken including only those players whose ages were under 28 and goalkeepers whose ages were under 32. The purpose of this analysis was to identify players with potential that had been largely unrecognised up until the tournament. It was found that both the teams selected in this way were dominated by players from European clubs. Ninety-two percent of the top sixty players in the analysis were playing in European leagues with 85% playing in Spain, England, Italy, Germany, France or Russia.

AbstractSoccer is the most popular sport in the world. Despite this global popularity, European teams in contrast to African ones, have dominated the Fédération Internationale de Football Association (FIFA) World Cup tournaments for many decades. Therefore, the aim of this study was to examine the performance indicators that differentiated between African and European teams in the 2018 FIFA World Cup. Thirty matches played by five European (n = 15) and five African teams (n = 15) from the group stages of the World Cup were analysed using the InStat video system. The results showed that European teams had higher averages than African teams on the following performance variables: total shots, shots on target, goals scored from open play and set pieces, ball possession, short passes, medium passes, total passes, accurate passes and corner kicks. Therefore, soccer coaches should take note of these findings as they could serve as a benchmark for African teams to set trends and improve their performance at FIFA World Cup tournaments.

Transition moments play a major role in match outcome and constitute an important part of the soccer coaching process. Nevertheless, the body of literature on match analysis reveals a lack of knowledge regarding transition moments, particularly the defensive ones. This study aimed to analyse how several situational and performance variables were associated with different defensive transition outcomes. A sample of 977 defensive transitions from 15 matches of FIFA World Cup 2018 was coded using a bespoke observational system. Data were analysed through log-linear modelling and Pearson’s chi-square. Regarding performance variables, final position ( p ≤ 0.001; ES = 0.390[≥0.290]; large effect size), duration ( p ≤ 0.001; ES = 0.206[0.07; 0.21]) , defensive approach ( p ≤ 0.001; ES = 0.419[0.30; 0.50]) , defensive pressure ( p ≤ 0.001; ES = 0.147[0.05; 0.15]; medium effect sizes), numerical relations ( p ≤ 0.05; ES = 0.113[0.07; 0.21]) , initial position ( p ≤ 0.05; ES = 0.092[0.06; 0.17]) , initial number of zones ( p ≤ 0.05; ES = 0.083[0.05; 0.15]) , final number of zones ( p ≤ 0.001; ES = 0.112[0.05; 0.15]) and defensive coverage ( p ≤ 0.001; ES = 0.130[0.05; 0.15]; small effect sizes) were significantly associated with the defensive transitions outcomes. A small-sized and non-significant association ( p = 0.126; ES = 0.080[0.07; 0.21]) was found for type of ball loss. Concerning the situational variables, a small-sized and significant association between match outcome and defensive transitions outcome was identified ( p ≤ 0.05; ES = 0.092[0.07; 0.21]). Our findings provide new knowledge on factors that influence team success in defensive transitions. The coaching staff should be aware that the exploitation of areas behind the most retreated player of the midfield sector ought to be avoided. Furthermore, a reduction in the space available to ball carriers and an increased effort to quickly recover possession should be encouraged.

This study explored how the video assistant referee (VAR) has influenced match performance variables at Fédération Internationale de Football Association (FIFA) World Cup tournaments. Comparative analysis was undertaken of matches played during the FIFA 2018 World Cup ( n = 64) tournament, where VAR was employed, and those played during the 2014 World Cup ( n = 64) tournament, where VAR was not employed. The following performance variables were recorded and analysed for each of the matches played: goals, penalties, corner kicks, yellow cards, red cards, offsides, playing time during the first half, playing time during the second half and total playing time. After the introduction of VAR, there were significant ( p < 0.05) increases in the number of penalties, as well as playing time during the first half, second half and total playing time. In contrast, a significant ( p < 0.05) decline was observed in the number of offsides after VAR was implemented. The current findings have practical implications for improvement of VAR implementation guidelines at FIFA World Cup competitions.

AbstractWe conducted an audit experiment to examine whether street vendors in Bogotá (Colombia) exert price discrimination based on buyers’ attributes, such as gender and nationality, and based on product characteristics, such as the increasing marginal valuation of items needed to complete a collection. We exploited the seasonal demand for album stickers related to the FIFA World Cup Russia 2018. In our within-subjects design, experimenters carried out in-person audits and quoted a pre-determined list of missing stickers. They interacted with 59 sticker vendors located in five geographic clusters and collected 287 vendor–buyer interactions. We find that prices quoted to foreign buyers are higher than prices quoted to Colombian buyers. By contrast, we do neither find evidence supporting direct gender-based discrimination, nor that vendors charge a higher price per sticker when the list of missing stickers is shorter. We complement the study with a qualitative analysis based on interviews that reveal vendors’ pricing strategies, their awareness of price discrimination, and the trade of counterfeits. The qualitative results suggest that price discrimination appears to be unconscious.

This study examines whether increases in incidents of female domestic abuse occur during FIFA world cup tournaments, in countries, other than the UK. Columbian medical records providing national daily counts, relating to Violence Against Women (VAW) and females subject to Intimate Partner Violence (IPV), across two world cup tournaments (2014/2018) were analysed. The number of medical examinations rose by 43% (VAW) and 39% (IPV) during the 2014 Columbia match days, and 26% (VAW) and 27% (IPV) during the 2018 match days, when compared to non-match days (p < .001). The increases were higher on a weekend and when winning, rather than losing.
