**Lazio vs Atalanta: Expected Goals (xG) Step Plot**

The diagram above summarizes every shot taken by Lazio (17 in total, 5 on target) and Atalanta (22 in total, 9 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 Luis Muriel (23′, 28′), Alejandro Papu Gomez (37′), Ciro Immobile (69′, 90+2′) and Joaquin Correa (70′). The coloured bar in the top left shows the probability of the Lazio winning the match (38%), Atalanta winning the match (38%), or a draw occurring (23%). Better known as a summary of all simulations, the y-axis represents the cumulative xG – how many goals should be scored – and the x-axis represents time. The Biancocelesti had a cumulative xG of 2.45 and the Nerazzurri had a cumulative xG 2.48.
