My previous post presented my Expected Saves model, and I thank everyone for the response and interest when I tweeted it a few days ago. In this post I’ll apply this model to goalkeeper performance in the previous Primera División championship in Argentina.This analysis takes DataFactory’s match event data from the tournament and calculates expected […]
When I first wrote about expected goals a few months ago, I said that the idea of expectation had spread into analysis of other plays and events in a football game — assists, passes, penalty kicks, even defensive movements. In this post I’m going to write about statistical expectations at the #1 position: expected goalkeeper […]
In addition to expected goals, passing network analysis has become a key element in soccer analytics. I’ve written about network analysis in a couple of Paper Discussions, but haven’t gotten around to exploring the concepts on data from a football competition. I’ll start now with an analysis of which players were most influential in the […]
At the midpoint of the 2016-17 Argentine Primera División season, I conducted an analysis of the refereeing performance in the competition that focused more on match management — time added on, time between stoppages, and effective time.

A continuación analizo las medidas de rendimiento para examinar la conjetura que Boca Juniors salió campeón por falta de un rival que podía dar una batalla sostenida.Me motivó esta nota de Cristián Grosso que apareció en […]
There are a number of narratives that one can use to describe the recently concluded Primera División season in Argentina, and I hope to explore some of them in future posts that review the championship. In this post I’m going to look at the performance metrics to assess the conjecture that Boca Juniors won the […]
Argentina’s Primera División 2016-17 has been a study of constants and fluidity since it began last August. Boca Juniors have led the tournament since December, but at least two and as many as five other sides have appeared as credible challengers to the title. Some teams should have been stronger challengers but haven’t (Racing Club), […]

Here’s an update after the most recent matches played last weekend (Round 25).Below is the offensive performance chart for Primera as of Round 25. The actual and expected goals are reported for open play events, set […]
