The purpose of this study is to identify the temporal and spatial characteristics of pass accuracy by utilizing the second processing data and official records collected from the 2018 FIFA World Cup Russia video data. For a total of 128 games, the success rate of passes based on the results of the game, passing time, and passing position was two-way ANOVA with repeated measure. The results showed no difference between winning and losing groups, and no interaction effects were found for passing time and location. The difference in passing time was high in the first half, with the highest success rate in the middle of the first half (79.2%) and the middle of the second half (77.9%) in the 15~30 minutes and the 60~75 minutes. Pass success rates were in the order of defense-midfield area (83.9%), midfield-attack area (81.7%), defense area (70.6%) and attack area (61.1%). In conclusion, there was no difference in the passing success rate of the winning and losing teams depending on the characteristics of the relative competitive strength of the World Cup games, and it is believed that follow-up research is needed to analyze the game contents rather than the factors of the winning and losing in the future.

This study used data of soccer match 5170 games from 1950 to 2008 in five European football professional leagues. We compared average of SGPG (scored goal per game) in each two and three points of win. And we compared average of SGPG in each leagues. In order to predict PtsG (points per game), we executed regression analysis using SGPG and LGPG (lossed goal per game). Finally, We applied regression analysis to a K-league.

Purpose: The purpose of this study is to explore, extract and categorize the team's tactical factors in soccer matches. Tactical factors are extracted on the basis of the phases consisting a football match (attack, defense, attacking transition, and defensive transition). Research design, data, and methodology: A semi-structural interviews were conducted with a group of experts of five football managers and coaches to explore tactical factors. Analysis of the content was done using a categorical aggregation or direct interpretation, and then was conducted factorial extraction and categorization. Results: In the attack phase, a direct attack and a step-by-step (occupation) attack form the type of attack, and in the attack transition phase, a long counter attack and a short counter attack form the type of attack. The type of defense in the defense phase was divided into regional defense and compression defense, and the type of defense in the defense transition phase was divided into defense for delaying counterattacks and defense for immediate pressure. Each tactics appeared differently depending on the situation of the game and the play of style. Conclusions: It may indicate the team's performance and has the potential for being used as a team performance factor. Further implications were discussed.
