How long do actions echo? ⚽️🔊 🇮🇹 A few weeks ago I was back at the #MLSA workshop, held during ECML/PKDD in Napoli. 🔜 I presented our latest study on possession value frameworks, where we analyse the “near future” over which the effect of an action is measured.

Another paper that we presented this week at MLSA briefly looks in the challenge of modelling out-of-distribution shots with boosted trees (and why TabPFN does it better). dtai.cs.kuleuven.be/events/MLSA2...

In the last chapter of her PhD thesis Lotte Bransen looked at penalty kicks. Several interesting things emerged. A simulation study indicated slightly higher save percentage if the goalkeeper did not always align directly in the center of the goal. 1/5

With a few days' reflection, my post-mortem on the United States men's national team at the 2026 World Cup. @theguardian.com www.theguardian.com/football/202...

The US delivered their best modern World Cup performance – and also let themselves down
Mauricio Pochettino’s team delivered several thrilling performances on home soil. The way it ended was somewhat less exhilarating

🥾⚽️ As noted by, e.g., @zonal-marking.bsky.social a strange trend of the 2026 World Cup is teams deliberately booting the ball out of play from kick-off. With the @royalbelgianfa.bsky.social we looked into this in 2024 for the @statsbomb.com conference.

I profiled U.S. men's national team starting goalkeeper Matt Freese, a pro athlete and Harvard grad who is somehow the underachiever in his remarkable family. Spoke to him and his family on their dynamics and Matt convincing his late, famous neurosurgeon father that soccer was worthy. @espn.com

I've always wondered (and feared) what might happen if everyone started taking set pieces seriously. The first eight weeks of the Premier League season might be giving us a glimpse into the future, where soccer no longer features much, well, soccer: www.espn.com/soccer/story...

Are set plays ruining the Premier League? How throw-ins are boosting Arsenal, but adding boredom
As Premier League teams learn set pieces are a more efficient way to score, open play goals become rarer. Can the game withstand such a shift?
