“…Technical performance data were collected from the website of Champion, 1 a leading Chinese sport data company. The validity and reliability of the Champdas Master Match Analysis System was verified by Gong et al (2019), who demonstrated that Aiken's V averaged 0.84 ± 0.03 and 0.85 ± 0.03 for the validation of indicators. Moreover, high kappa values (Operator 1: 0.92 and 0.90; Operator 2: 0.91 and 0.88), high intraclass correlation coefficients (varied from 0.93 to 1.00), and low standardized typical errors (varied from 0.01 to 0.34) indicated a high level of intraoperator reliability.…”

The aim of this study was to explore the effect of scoring first on match outcomes in the Chinese Football Super League (CSL). A total of 1,116 matches in which at least one goal was scored from the 2014 to 2018 seasons were collected. Match outcomes, absolute goal differences, the minute of the first goal, match locations, and teams’ budgets were analyzed. A team’s budget was measured in terms of a team’s value at the beginning of the season, and teams were clustered into two groups (high and low budget with means of 50.77 and 13.77 million dollars, respectively). A descriptive analysis was conducted, and two generalized linear models (a multinomial logit model and a Poisson model; p < 0.05) were applied. The results showed a favorable outcome for the team that scored first both in match outcome and goal difference. Regarding the teams that scored first, 66.31% won their matches, 20.70% achieved a draw, and 12.99% lost. Specifically, home teams were more likely to win (13.42%) and less likely to lose (9.52%) or draw (3.90%) than away teams. Home teams also had a higher likelihood of obtaining a larger goal difference. Higher budget teams were more likely to win (14.90%) and less likely to lose (9.75%) or draw (5.14%) than low-budget teams. Additionally, for each minute, the team scores closer to the end of the match, and the average probability of winning increased by 0.0028. These findings can guide the strategies of coaches in different match scenarios according to the match location and the opponent’s quality.

“…The inter-player passing statistics of all matches were tracked and provided by the Shanghai Champion Information Technology Co., Ltd. through a validated data collection system (Champdas Master System, http://www.champdas.com) operated by trained collectors, and they have at least two years of experience in operating the system. 3 The starting players and substitutes were all included. However, as the study only considered the passing performance of outfield players when teams were in possession of the ball, after organising the data, any inter-player passing count less than five passes was ruled out, and goalkeeper-involved passes were also excluded during the filtering process.…”

“…Computer-based approaches have been applied to collect and analyse technical, tactical and physical aspects in team sport, especially in football, and progressively increased the information and dimensions related to the study of match performance behaviours. 1–3 Recently, the general structure of football teams and connections among players during match-play were investigated using social network analysis (SNA). 4–7 Contrast to the traditional notational analysis, the SNA considers and models passing distribution of teams and is proved to be useful since its concepts and methods could not only illuminate player’s or team’s dynamics, but also improve the understanding of complex relational interactions within the team.…”

The study was aimed to identify the passing performances related to social network between domestic (Chinese) and foreign (non-Chinese) players that contributed to the offensive play according to playing positions in Chinese Football Super League. Data were collected from all 16 teams, with 63,446 passes from 8885 player observations of 346 unique players (258 domestic and 88 foreign) being filtered. Nine network metrics were adopted to assess the passing performance between two player groups. The results revealed that foreign players, especially midfielders and forwards, had increased values than domestic counterparts in passes in, indegree, stress, partner and betweenness centrality (standardised Cohen’s d range: 0.18–0.62; inference: possibly to most likely). Moreover, foreign midfielders also demonstrated higher values in passes out, outdegree and closeness centrality (0.30–0.56; likely to most likely). The analysis of passing performance allows for a better understanding of team’s attacking properties and highlights the prominent role foreign players act within the build of attack. It is possible that recruiting high-level overseas players contribute to Chinese teams’ goal scoring performance, but coaching staffs and team managers should take cautions in terms of the degree of reliance on them, as the development of domestic midfielders and forwards would be compromised.

The outbreak of COVID-19 forced Chinese Football Association to adopt a special format for the 2020 Chinese Football Super League (CSL) after 5-month suspension. All 160 matches (decreased from 240) were divided into two stages (round robin; two-legged knockout) and played behind closed doors in two neutral cities (Suzhou and Dalian). The purpose of this study was to investigate the influence of absence of spectators and format change on teams’ winning percentage and match performance. Technical-tactical and event data of all 400 matches during 2019 and 2020 seasons played by 18 teams were collected. A total of 26 performance indicators were extracted and standardized from the original data. The independent t-test results showed that there were statistically significant differences in 13 performance indicators between 2019 season home win and 2020 season win: shot, shot not on target, simple pass, pass, pass accurate, key pass, corner, corner accurate, dribble and take on (p<0.025, absolute ES: 0.28-0.74) for player performance as well as defensive fouls, defensive third foul and yellow cards for referee decision-making (p=0.001, absolute ES: 0.42-0.45). And there were statistically significant differences in 16 performance indicators between 2019 season home not win and 2020 season not win: shot, shot not on target, touch, simple pass, pass, pass accurate, key pass, corner, corner accurate, dribble, defensive duel, penalty shot and clearance for player performance (p<0.04, absolute ES: 0.21-0.93) as well as defensive third foul, defensive foul and yellow card for referee decision-making (p<0.015, absolute ES: 0.29-0.43). The findings implied that the change of match locations and absence of team supporters led to a decrease in teams’ match performance and an increase in referees’ decision. Although top-ranked teams seemed to be unaffected and the low-ranked teams showed an increase in winning percentage, the fairness of such tournament format needs to be reconsidered.
