Sabermetrics applying to Soccer

Does anybody know of any available published or online information about individual match performance data for youth.
I am interested to know if anyone is studying or has studied performance statistics such as passing accuracy, etc and how they tend to develop over time with age.
Was Xavi 90+% passing accuracy when he was 14? 18? I'm thinking people were not tracking the things at the time.
Are professional teams using stats for the youth teams? How about National youth teams?
If so how do they compare to professional Big 5 or MLS numbers?

 

Here are a few different statistics I worked on for the US World Cup roster. Let me know what you think!

Reworked one of yesterday's statistics. Hopefully it is clearer now.

Added some individual possession stats today.

Off-topic, so with apologies, but saw it and liked it ...

I am not a stats guy, but I think the article is worth reading and might provide some insight. Enjoy!

 

I think it is a good thing.

You can also use some free mobile apps to record statistics. As a coach, I have find apps useful for analyzing game performance. Of course, you need to find a volunteer to record the game since it would require full attention. Recently I have used PreciseStats for Soccer Android app: https://play.google.com/store/apps/details?id=com.precisestats.soccer

 

Statistics is the most important thing!
Some good stats for soccer:

The stats I would like to see deployed more are the player and team performance stats. This would be more the strategic info that only coaches and ATs would have on their team. I would love to put sensors/GPS/accelerometers/heart rate monitors on my teams.

 

Oh, and here's a great analytics in sports paper that really breaks is down.

Wow this is a great post. Do you guys think the SPI ratings are done well?

 

Fascinating thread. We've been working on a statistical system that separates stats that are predictive of outcomes vs. those that are descriptive / good to know. For instance, on possession, we found that passes completed has a very low correlation to outcome - except passes not completed in the back third. However, for possession, ball movement forward has a much higher correlation to outcomes - scoring as well as preventing the opposition from scoring.

We are working on putting our full methodology out there - for now, we distilled the outcomes across possession/defense/offense/goalkeeping in to letter grades. We are also working on making the underlying stats available. (Underpinning this is 5+ years of data across Champs League, La Liga, Premier League and MLS)

We would really appreciate feedback and suggestions for improvement as we build out more of the system and website.

There are good football statistics website

Im too stupid to even grasp what that means

 

This last point is how I see the next major development in player data collection - will soon be adopted in the Rules of the Game by FIFA too to officially allow chips etc to be embedded in shirts.

 

Saw this piece of analysis a few weeks back on the MLS (one of the few leagues that publish salary data) and to me, this is what clubs should be doing.....essentially monitoring performance by cost. If only other leagues would publish this kind of data and the transparency was there, it would be fascinating to see it across the major European leagues.

Hi guys,

Please take a look at my project l2bet.com. First of all, it’s all free. I have Academic education in the field of psychology and I like to apply psychological andphilosophical facts to the field of betting and creates a whole new perspective for the bettors

 

Since you guys understand statistical information. Why do they keep secondary assists. A pass that leads to another. It just a pass a pass that leads to a goal I can see. But the secondary just adds to his assist total. It means nothing as far as the players field vision is concerned.

 

I don't know if that questions requires knowledge of statistics to answer. Do any leagues other than MLS keep track of secondary assists? I'm not sure, but it's possible that MLS keeping track of secondary assists should be grouped with drafts and the lack of promotion and relegation as differences between MLS and leagues in most countries. That sentence is not meant to imply a point of view of any of those differences being good or bad.

 

There was a time when no league kept a record of assists a player made.

There also was a time when the team with the best record won the league champion. There was no playoffs this is an American invention to make more money.

 

Not sure if already posted... but I believe Everton just hired someone involved in that movie etc... statistical analysis etc. http://www.espnfc.us/english-premie...alsh-could-be-the-transfer-coup-of-the-season
