A collaboration between The Laziali and Cheuk Hei Ho has been established. Focusing on traditional video analysis and a data-driven approach to analyze football tactics and strategies, here, you will find in-depth data concerning Lazio’s matches. From the quantity and location of shots to expected goals and pass networks, we are extremely happy to announce this partnership with Cheuk. You can visit Tactics Platform to view more of his work on statistical analysis.
There will be three separate analyses created by Cheuk for each match.
The first is an Expected Goals (xG) Step Plot. This summarizes every shot taken by either side 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. The colored bar in the top left shows the probability of the home side winning the match, the away side winning the match, or a draw occurring. 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. Please refer to the example above.
The second is an Outcome Probability Bar Chart. Each chart is a summary of a 10,000-time simulation of the probability of how many goals each team should have scored; the colored bar is the actual number of goals each team scored. Please refer to the example above.
The third is a combination of a Pass Network Plot and a Shot Location Plot. The former summarizes 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. The latter 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. Please refer to the example above.
