Which teams are most consistent? The x-axis is average xG difference (the difference between xG and xG conceeded), and the y-axis is the standard deviation of xG difference, which measures variability. The dashed lines are the league averages. Teams in the bottom right quadrant are strong and reliable. Teams in the top right quadrant are streaky — they're good on average, but unpredictable from match to match. Teams in the top left quadrant are erratic — they're bad and unpredictable.
