Well now they are being used to say what the result should have been.

We should have lost to Chelsea by 1.56 to 0.63.

'Expected goals' is a statistic used to work out how many goals should be scored in a match, with every shot taken given an 'expected goal' value based on the difficulty of the attempt.

Based on a number of factors including distance from goal, type of shot and number of defenders, the 'expected goal' value reveals the likelihood a specific shot will end in a goal; the higher the value, the more likely a goal should be scored from that shot

The 'expected goal' value of every shot in a game is used to calculate the 'expected goals' (xG) of a match. Click here to find out more about the calculations used to work out xG.

Should a team end with a higher xG than actual goals scored, it is probable they were wasteful in front of goal due to poor finishing or an in-form opposition goalkeeper. If the real goals scored is higher than the xG, the team have been lucky to score so many???

Lucky no just class
