What data did Qatar 2022 give us for the start of Argentine soccer?

Soccer is a complex game, with few repeating patterns and parameters compared to other sports. That is why he was one of the last to take metrics. Simple stats like shots on goal or passes are easily quantifiable but the overall effects of those passes require other factors as well as some skillful interpretation.

Nothing that happens in a football match is an isolated event, except for the shot from a penalty.

The extracted data is then clippings from the game itself, produced by the game’s performance data and analysis team. fifa (“High performance” and “Analysis and information on soccer”). Group founded in early 2020, with the intention of “improving the understanding and experience of soccer by combining technical expert observations and soccer data analysis.”

arsene wenger is the head of the structure, who is in charge of the football development area at a global level for the fifa. He is accompanied by other famous ex-soccer players and coaches such as Jurgen Klinsmann, alberto zaccheroni Y Faryd Mondragonplus a group of analysts, engineers and data scientists.

viewers of Qatar 2022 They must have seen on the screen when some of these new metrics were appearing in graphs known as “Enhanced Football Intelligence (EFI)”. These figures are added to those registered as fouls, corner kicks and cards to present a more complete picture of the dynamics of the match.

For the EFI assembly process to work, two data sources were required. What happened around the ball as a shot, a foul or a pass and the live punctual monitoring data of each player.

From the fusion of the two data sources in each “event/fact“What happens, a record is taken and then it is contextualized with the position and actions of the other players in relation to that event. Finally, that event and what surrounds it are processed with algorithms designed in data science to give it a referenced value.

An example is the variable “passes that break lines”. Shipments that go through a complete unit of the defending team and are received by a teammate behind the line.

This data, which may be insignificant for a neophyte, is key for coaches because there is a very strong direct proportional relationship: the greater the number of line breaks conceded, the greater the chances of losing the game.

Another new fact that was seen in this world It was the aggregate, in the time of possession, of the minutes in dispute. 100% possession is no longer binary as before, but time with disputed values ​​enters as a disputed third party.

By way of enunciation, in addition to the two metrics mentioned (broken lines and control of possession), there are nine under consideration:

  • Ball recovery time.
  • Defensive line height
  • Equipment length.
  • Forced turnovers.
  • Tickets to the final third of the rival field.
  • Pressure on the ball.
  • Team form.
  • Expected Goals: The probability that a shot will result in a goal.
  • Phases of the game: time spent by a team with or without the ball and chosen disposition (high pressure, counterattack, etc.)

This was the primer world Cup with shared data, which is no longer owned by the teams, but is open to the public.

The reports of all the matches are freely accessible to anyone who wants to review them on the FIFA website (Source: https://www.fifatrainingcentre.com/en/fwc2022/post-match-summaries/post-match-summary-reports.php) and not to mention if you were the handle of the World Cup where you have the possibility of seeing the game again comparing with the data at hand. That way, you better wait for the start of the championship and you understand a little more about the game.
