Fiorentina vs Lazio: Expected Goals (xG) Step Plot
The diagram above summarizes every shot taken by Lazio (12 in total, 7 on target) and Fiorentina (11 in total, 3 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 Joaquin Correa (22′), Federico Chiesa (27′), and Ciro Immobile (89′). The coloured bar in the top left shows the probability of the Lazio winning the match (61%), Fiorentina winning the match (14%), or a draw occurring (24%).
