is shown in blue. A high efficiency corresponds to a slope $\alpha>1$, $\alpha<$ to a low efficiency. The axis section $g_0$ indicates how many goals a team scores in games with equal scoring chances ($xG_{G}\simeq 0$). The larger the axis segment, the more often the team has won, conversely a large negative axis segment means that thigt games are often lost. | is shown in blue.
