Python code associated to my blog post about Messi: Is it possible to defend against Messi?.
This repo contains code for analysing Messi Data Biography.
It contains folders for Jupyter notebooks, data, and figures.
My analysis is composed of several notebooks. You can find the complete list below, with a small description.
| Notebooks | Description |
|---|---|
| 01-data_loading | Load Statsbomb data from local or github and do some preprocessing. |
| 02-data_exploration | Explore Messi data and visualize some stats (goals, winning %, etc.) |
| 03-Defense_analysis | Focus on the question "How to defend against Messi?". Exploration of Espanyol-Barcelona 2009/2010 |
| 04-VAEP_with_atomic-spadl | Use atomic-spadl to use the VAEP metric |
| 05-xT_with_atomic-spadl | Use atomic-spadl to use the xThreat metric |
| 06-EXTRA-advanced_messi_stats | Data vizualisation of some advance metrics |
| atomic-spadl_1-load-and-convert-statsbomb-data | Notebook from atomic-spadl |
| atomic-spadl_2-compute-features-and-labels | Notebook from atomic-spadl |
| atomic-spadl_3-estimate-scoring-and-conceding-probabilities | Notebook from atomic-spadl |
| Utility_functions | Utility functions for data vizualisation and calculate advance stats |
| unit_test | Test of one utility function with pytest |
N.B.: make sure the atomic folder of socceraction is at the same level as this project if you want to use the associated notebooks.
