In the field of football analytics, the goal is to improve (in terms of prediction performance) one of the emerging tools: the expected goal (xG) model. With this final aim, data from different sources have been merged: tracking data, match event data and some players’ performance composite indicators obtained using a Partial Least Squares - Structural Equation Model (PLS-SEM) approach. Using a sample of match data relying to season 2019/2020 of the Italian Serie A, composed by 1 outcome variable (i.e. the GOAL) and 22 features, a logistic regression model was applied on different scenarios for sample balanced techniques.

Abstract

In the field of football analytics, the goal is to improve (in terms of prediction performance) one of the emerging tools: the expected goal (xG) model. With this final aim, data from different sources have been merged: tracking data, match event data and some players’ performance composite indicators obtained using a Partial Least Squares - Structural Equation Model (PLS-SEM) approach. Using a sample of match data relying to season 2019/2020 of the Italian Serie A, composed by 1 outcome variable (i.e. the GOAL) and 22 features, a logistic regression model was applied on different scenarios for sample balanced techniques. Results seem to be interesting in terms of sensitivity, F1 and AUC metrics, compared with a benchmark. In addition, some original performance composites and tracking variables introduced are significant for the classification model.
