In Matchday 27 of the 2019/20 Serie A, Simone Inzaghi’s **Lazio** were defeated by Gian Piero Gasperini’s **Atalanta** 3-2 at the Gewiss Stadium. Below, a statistical analysis of the game between the Biancocelesti and the Nerazzurri.

**Expected Goals (xG) Step Plot**

*The diagram above represents a summary of all simulations. The y-axis represents the cumulative xG (how many goals should be scored) and the x-axis represents time. ***Lazio** had a cumulative xG of **0.36** and **Atalanta** had a cumulative xG of **2.45**.

*In addition, the diagram above summarizes every shot taken by each club. 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. *The **Biancocelesti** had **7 total shots (3 shots on target)** and the **Nerazzurri** had **24** total shots **(7 shots on target)** in the match.

*Furthermore, a dot with a name on the ‘Expected Goals Step Plot’ represents when a goal was scored and who the goal was scored by. *As pictured above, the goalscorers were **Marten de Roon **(5′), **Sergej Milinkovic-Savic** (11′), **Robin Gosens** (38′), **Ruslan Malinovskiy** (66′), and **Jose Luis Palomino** (80′).

*Finally, the colored bar in the top left of the diagram shows the probability of each club winning the match or a draw occurring. *The probability of **Lazio** winning the match was **3%,** the probability of **Atalanta** winning the match was **86%,** and the probability of a **draw** occurring was **11%**.

**Outcome Probability Bar Chart**

*The charts in the diagram above are a summary of a 10,000-time simulation of the probability of how many goals:* **Lazio (most likely 0)** and **Atalanta (most likely 2)** should have scored; the colored bar is the actual number of goals the **Biancocelesti (2)** and the **Nerazzurri (3)** scored.

**Pass Network Plot & Shot Location Plot**

*The diagram above firstly shows the number of passes completed by each side in the match. *Overall, **Lazio** had **395 passes** with a **74.2% accuracy rate** while **Atalanta** had **600 passes** with an **83.2% accuracy rate.**

*Secondly, the diagram outlines the most active players for each team. Each player is represented by a node; t**he size of each node denotes the number of touches each player had. ***Lazio’s** most active players on the ball were **Thomas Strakosha, Patric, Sergej Milinkovic-Savic, Manuel Lazzari, **and **Francesco Acerbi;** **Atalanta’s** most active players on the ball were **Alejandro Gomez, Remo Freuler, Hans Hateboer, Marten de Roon, **and **Berat Djimsiti.**

*Thirdly, the diagram indicates the pass connections between teammates. These connections are the shaded grey lines throughout the plots; the size and shade of the line between players indicates the frequency of a pass connection. It is important to note that t**he direction of each connection is not shown. *The five main connections for **Inzaghi’s** men were between **Strakosha-Patric, Patric-Lazzari, Patric-Milinkovic, Milinkovic-Lazzari,** and **Milinkovic-Immobile**; the five main connections for **Gasperini’s** men were between **Djimsiti-de Roon, de** **Roon-Hateboer,** **de Roon-Malinovskiy, Malinovskiy-Gomez,** and **Gomez-Freuler**. These aforementioned connections are outlined in **light blue (Lazio)** and **dark** **blue** **(Atalanta).**

*Finally, this diagram shows the coordinates of each shot. The shots are plotted as light grey dots while goals are plotted as dark blue dots. The size of each dot represents the xG; the bigger the dot, the higher the chance that this opportunity should have found the back of the net (been a dark blue dot). *As mentioned before, the **Biancocelesti** had **7 total shots (3 shots on target)** and the **Nerazzurri** had **24** total shots **(7 shots on target).**
