Cagliari vs Lazio: Expected Goals (xG) Step Plot
The diagram above summarizes every shot taken by Lazio ( in total, on target) and Juventus ( in total, on target) in the match. Each shot is represented by a step and the height of the step measures the xG outcome of that shot; the higher the step, the more likely that the shot taken should have been converted.
A dot with a player’s name represents when a goal was scored; as pictured above, the goalscorers were Giovanni Simeone (8′), Luis Alberto (90+3′), and Felipe Caicedo (90+8′).
In addition, the colored bar in the top left of the diagram shows the probability of the Lazio winning the match (46%), Cagliari winning the match (28%), or a draw occurring (26%).
