### Lazio vs Lecce: Expected Goals (xG) Step Plot

The diagram above summarizes every shot taken by Lazio (24 in total, 7 on target) and Lecce (19 in total, 10 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 (30′, 80′), Gianluca Lapadula (40′), Sergej Milinkovic-Savic (62′), Ciro Immobile (77′), and Andrea La Mantia (85′). The coloured bar in the top left shows the probability of the Lazio winning the match (75%), Lecce winning the match (12%), or a draw occurring (14%). 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 4.14 and the Giallorossi had a cumulative xG of 2.33.

### Lazio vs Lecce: Outcome Probability Bar Chart

Each chart in the diagram above is a summary of a 10,000-time simulation of the probability of how many goals Lazio (most likely 4) and Lecce (most likely 2) should have scored; the colored bar is the actual number of goals the Biancocelesti (4) and the Giallorossi (2) scored.

### Lazio vs Lecce: Pass Network Plot & Shot Location Plot

The diagram above firstly shows the pass connection between players, represented by nodes. The size of each node denotes the number of touches each player has while the size and shade of the line between players indicates the frequency of the pass connection. The direction of the connection is not shown. As seen, Lazio’s most active players on the ball were Patric, Luis Alberto, and Luiz Felipe; Lecce’s most active players on the ball were Panagiotis Tachtsidis, Luca Rossettini, Marco Calderoni, and Jacopo Petriccione. In addition, the five main connections for Inzaghi’s men were between Acerbi-Luiz Felipe, Patric-Luiz Felipe, Lazzari-Milinkovic, Lulic-Luis Alberto, Correa-Luis Alberto; the five main connections for Liverani’s men were between Calderoni-Rossettini, Lucioni-Rossettini, Meccariello-Lucioni, Tachtsidis-Petriccione, and Calderoni-Petriccione. These aforementioned connections are outlined in light blue (Lazio) and dark blue (Lecce). Secondly, this diagram shows the coordinate of where each shot was taken, plotted as dots. The size of the dot shows the xG; the bigger the dot, the higher the chance that the ball should be finding the back of the net. Colored dots represent goals. Overall, Lazio had 538 passes with an 83.5% accuracy rate while Lecce had 423 passes with an 81.3% accuracy rate.
