Resumo

A abreviatura de Golo esperado é xG nas estatísticas do futebol. O xG mede a qualidade de uma chance calculando a probabilidade de esta ser marcada numa determinada posição do campo durante uma determinada fase do jogo. O objetivo deste estudo foi avaliar a métrica xG em termos de variáveis ​​contextuais, como a situação das equipas na mesa final, a situação do jogo e o local. As pontuações xG das equipas (n = 760) dos 380 jogos da temporada 2021-2022 da Superliga Turca foram recolhidas para este estudo. As variáveis ​​contextuais indicaram o seguinte; o nível de sucesso, o estado de sucesso e a vantagem das equipas. Assim, os grupos foram organizados da seguinte forma; a classificação da mesa final foi de cinco grupos (i.e., quatro primeiras equipas, duas quatro equipas,…), o estado do jogo foi de três grupos (vitória, empate e derrota) e o local foi de dois grupos (casa, fora ). Os resultados mostraram que as equipas com melhor classificação obtiveram xG mais elevados do que as equipas com classificação inferior. As primeiras quatro e segundas quatro equipas foram significativamente superiores às quintas quatro equipas. As pontuações xG das equipas vencedoras foram significativamente superiores às do empate e das vencidas. As equipas da casa também alcançaram uma pontuação xG significativamente mais elevada do que as equipas visitantes. Os resultados sugerem que a métrica de golo esperado (xG) pode avaliar o sucesso das equipas.
