Just a reminder that you are not obligated to argue with every sub-literate plonker online. Gandalf the White did not pass through fire & death to bandy crooked words with witless worms, and nor should you.
@graham_hunter68@wsa345@footballontnt I'm not 100% sure, but I believe its post shot xG minus goals conceded.
So if the post shot xG is 10, and you've conceded 8 goals, you've prevented 2 goals. Using basic numbers for simplicity
@bethTmufc Problem I notice with Martial is he doesn't make the final runs with purpose inside the 18. Great dropping in during buildup but not offering an actual goal threat when we get into the final third
