The aim of this research was to determine and identify the number of completed successful attacks of the four first-placed teams (France, Brazil, Croatia and Netherlands) at the 1998 16th FIFA World Cup in France and the four first-placed teams (Italy, France, Germany and Portugal) at the 2006 18th FIFA World Cup in Germany, for each team individually. In this research, the samples taken from the population at large can be defined as active, professional, elite players in the regular, biggest, and strongest system of competition - the FIFA World Cup. For the realization of this study, measures of descriptive (frequency distribution) and comparative (X² - test and multiple classification test) statistics were used. The results obtained at both World Championships were analyzed by all the criterion variables and provided the ability to define specific actions that can be recommended for a statistical and systematic monitoring of successful attacks. Based on these results, it is possible to identify the importance of successful attacks (inaccurate, accurate and efficient) in order to achieve maximum competitive success and determine the best ways to set up a methodology of training activities.

Women's Football

Women’s football is the sports game with the most spectacular development in recent years both in terms of the number of participants (approximately 40 million) and all other factors involved in this process (international federations, investments, spectators, etc.). The general perception that most specialists have about women’s football is: “Like amateur football, but in slow motion”. This perception has fundamentally changed with the significant improvement in the level of performance shown on the field by football players. The questions we are trying to answer by conducting this research are the following: Are there important technical and tactical differences between women’s and men’s high-performance football? If there are such differences, what relevance do they have for the preparation process? In this context, the present study represents a comparative analysis, from a technical and tactical point of view, of the teams ranked in the top 3 at the last World Cups for both men (2018 FIFA World Cup Russia) and women (2019 FIFA Women’s World Cup France). The data were obtained from the FIFA website and from live statistics provided during each World Cup game. The conclusions that will emerge from this study may represent directions for the further technical and tactical development of women’s football.

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.

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.

Abstract A new simple computational tool is proposed for the synthesis of multi-section coupled-line filters based on combined modified planar circuit method (MPCM) and transmission line method (TLM) analysis, referred to as MPCM-TLM. Due to its fundamentally simple architecture, the presented tool offers significantly faster optimization of coupled-line filters – for exactly the same initial simulation set-up – than other costly commercially-available tools, giving equally reliable results. Validity and accuracy of the proposed tool have been verified through the design of 3rd, 5th, and 7th order coupled-line filters and comparative analysis between results obtained from the proposed approach and the high-frequency structure simulator. A remarkable 99% time reduction in the analysis is recorded in the case of 7th order filter using the proposed tool, for almost identical results to HFSS. Therefore, it can be confidently claimed that the proposed technique can be used as a reliable alternative to existing complex, costly, processor-intensive CAD tools.
