We have loads of them.
Other teams not so much.
But seriously, I think it's what's deemed a really good chance. For example KDBs goal today was probably a .25 expected goal. Jesus' goal was probably a 1.0. A bit of a silly statistic IMO.

If that is correct then it would also suggest an air kick in front of an open goal wouldn't fall in to 'expected goals'.
To conclude, I call bollox on it m'lud.

I don’t care too much for the total numbers but the graphics like Saul showed above give a good representation of how the match went. The one omission is opportunities that didn’t result in a shot.

I still.dont get it. I saw Everton and palace both had less than 2 xg but the game ended 2-2? I must be getting old as this is just nonsense in my head

I rekon it is just a fad and will sink to the background noise after a while.
Probs one of the betting comps came up with it or someone then selling the data to the clubs.
It can be used at micro - player/game level and macro - team/season level
like City get av. 12 chances / game and as the xG is good cos we are clinical then we are likely to win a game or the league.
Can be used to show how clinical each player is also obviously.
this is a decent enough read... as it is about us basically

Why is xG useful?
xG's value is that it gives an indication of whether a team's results are based on sustainable factors like the consistent creation or denial of chances, or whether it is down to less sustainable factors like freakishly high chance conversion or sensational goalkeeping.
It also gives a far more reliable picture as to us the results of individual matches reflected the pattern of play. Take Germany's 7-1 win against Brazil in the 2014 World Cup for instance, in which Brazil actually had more shots and possession, but were way down on xG compared to their opponents.
xG can be thought of as effectively evaluating "chances", whereas "shots on goal" does not discriminate between a 35-yard sighter and a missed open goal from close range.By analysing every shot from last season and the season before, the STATS team have been able to identify a number of patterns, which we can use to inform how this season might pan out.

I quite like that it tries to add a qualitative element , its not perfect, but then all stats can be rendered useless. Shots off target for example - were they decent shots or all from 35 yards?
I don't think the name "Expected Goals" is great, should be Chance Creation, or something better than that.
