EPL Week 3 - xG Results

Who has never heard about xG (expected goals) - basically it is a probability of shot to converted into a goal. It is based on distance, actions leaded to shot (corner, set piece, cross, dribble) and attack speed.

https://understat.com/league/EPL/2017 - all results here. I chose the most interesting:

1. Crystal Palace - Swansea. Welsh team wasn't even close to win and fair result here is a draw.

2. Huddersfield - Southampton. Home team deserved a win and I'm going to follow them this season, because they have a lot analytics who work with big data

3. Tottenham - Burnley. It's easy - no luck on Wembley

4. Liverpool - Arsenal. Wenger loves big data, so he'll be sure that it wasn't a game when Liverpool scored every possible moment they had.

Anywhere I can read more on this?

I think Jay was asking about this related to the Ars-Liv game

Sooooo this is an analytical system based on statistics that shows what the outcome of a game is most likely to be???
