xG (Expected Goals)
Scoring difficult chances, as well as those that are handed to you on a plate, is another indication as to whether a player is a top drawer finisher.
xG measures how many goals a player should score given the chances provided to them. For Greenwood that number this season is 8.52. With his goal total standing at 12, it means he has overperformed by three to four goals; something only elite strikers do.
