How Sheffield United, Middlesbrough, Rotherham United, Hull City, Huddersfield Town, Sunderland and other Championship clubs have performed this season relative to their xG
xG and xGA are used to assign a value to goal scoring chances based on past performance data.
Comparing these values to actual goals scored and conceded can indicate whether a team is above or below average at taking or preventing goal scoring opportunities - or experiencing particularly good or bad luck around the goal.
