xG:
"Expected goal assigns a value to each shot between 0.00 and 1.00 to reflect the probability that it will result in a goal. A shot that measures 0.01 xG suggests it could reasonably be expected to result in a goal one in 100 times"
While I don't find it as accurate as it only counts shots, so for example if we put a striker in a good chance, but he fucks it up because of his heavy first touch and won't get to shot then it won't be reflected in xG Stat. So it can basically only show the quality of the shots he is putting, not the overall gameplay.

Something I never understood is who determines the value? Is it considered a universal fact by all, or do different sources give different xg? How on earth could you arrive at a factual figure for an event in a football game?
