The diagram above summarizes every shot taken by Lazio (12 in total, 5 on target) and Napoli (13 in total, 4 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 goalscorer was Ciro Immobile (82′).

In addition, the colored bar in the top left of the diagram shows the probability of the Lazio winning the match (41%), Napoli winning the match (27%), or a draw occurring (32%).

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 1.07 and the Partenopei had a cumulative xG of 0.82.

The diagram above 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 Stefan Radu, Francesco Acerbi, Luiz Felipe, Lucas Leiva, Senad Lulic, and Luis Alberto; Napoli’s most active players on the ball were Mario Rui, Giovanni Di Lorenzo, Fabian Ruiz, Elseid Hysaj, and Kostas Manolas.

In addition, the five main connections for Inzaghi’s men were between Radu-Lulic, Lulic-Immobile, Lulic-Luis Alberto, Acerbi-Luiz Felipe, Luiz Felipe-Lucas Leiva; the five main connections for Gattuso’s men were between Insigne-Mario Rui, Mario Rui-Di Lorenzo, Di Lorenzo-Manolas, Manolas-Hysaj, Hysaj-Callejon. These aforementioned connections are outlined in light blue (Lazio) and blue (Napoli).

In addition, 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. The colored dark blue dots represent goals.

Overall, Lazio had 441 passes with an 81.6% accuracy rate while Napoli had 768 passes with an 88.3% accuracy rate.
