Cheuk Hei Ho (Tactics Platform) focuses on traditional video analysis and a data-driven approach to analyze football tactics and strategies. Since 2019, in collaboration with The Laziali, Cheuk has provided in-depth data on Lazio’s matches with three separate types of analyses for each match. These include an Expected Goals (xG) Step Plot, an Outcome Probability Bar Chart, and a Pass Network Plot & Shot Location Plot.
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.
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.
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.
Finally, the colored bar in the top left of the diagram shows the probability of each club winning the match or a draw occurring.
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 each side should have scored and the actual number of goals each side scored.
Pass Network Plot & Shot Location Plot
The diagram above firstly shows the number of passes completed by each side in the match.
Secondly, the diagram outlines the most active players for each team. Each player is represented by a node; the size of each node denotes the number of touches each player had.
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 the direction of each connection is not shown.
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).
Thomas Gregg breaks down each of Lazio’s matches to find trends in both the attacking and defensive phases while also providing a brief tactical preview of the Biancocelesti’s next clash.
Steven Moore provides a detailed step-by-step replay of each of the goals scored by and conceded by Lazio.
