As gigabytes of data flow from field to fingertips, the technological divide has been closing between teams at the World Cup.
While the focus has been on the debut of video assistant referees, less obvious technical advances have been at work and the coaches have control over this area, at least.
No longer are the flashiest gizmos to trace player movements and gather data the preserve of the best-resourced nations. All World Cup finalists have had an array of electronic performance and tracking systems made available to them by FIFA.
“We pay great attention to these tools,” Poland coach Adam Nawalka said. “Statistics play an important role for us. We analyze our strength and weaknesses.”
The enhanced tech at the teams’ disposal came after FIFA approved the use of hand-held electronic and communications equipment in the technical area for tactical and coaching purposes.
That allows live conversations between the coaches on the bench and analysts in the stands, a change from the 2014 World Cup, when the information gathered from player and ball-tracking systems could not be transmitted in real time from the tribune.
“It’s the first time that they can communicate during the match,” FIFA head of technology Johannes Holzmueller said. “We provide the basic and most important metrics to the teams to be analyzed at the analysis desk.”
The key performance indicators fed by tracking cameras and satellites provide another perspective when coaches make judgements on substitutions or tactical switches if gaps exposed on the field are identified.
“These tools are very practical, they give us analysis, it’s very positive,” Colombia coach Jose Pekerman said. “They complement the tools we already have.”
Player welfare can also be enhanced with tools to assess injuries in real time allowed for use by medics at this World Cup. Footage of incidents can be evaluated to supplement any on-field diagnosis.
A second medic “can review very clearly, very concretely what happened on the field, what the doctor sitting on the bench perhaps could not see,” FIFA medical committee chairman Michel D’Hooghe said.
However, the technology is moving too quickly for some coaches.
“Football is evolving and these tools help us on the tactical and physiological side,” Senegal coach Aliou Cisse said. “We do look at it with my staff, but it doesn’t really have an impact on my decisionmaking.”
Panama coach Hernan Dario Gomez has reviewed the data feeds, but the team have been eliminated in the group stage after facing superior opponents.
“This is obviously very important information, but not more important than the actual players,” Gomez said.
The data is still reliant the quality of analysts interpreting it.
“You can have millions of data points, but what are you doing with it?” Holzmueller said. “At the end even if you’re not such a rich country you could have a very, very clever good guy who is the analyst who could get probably more out of it than a country of 20 analysts.”
FIFA’s technical staff will continue to innovate, but artificial intelligence is not taking over. For some time, at least.
“People think now it’s all driven by computers,” Holzmueller said. “We don’t want that at FIFA.”
BOUNCING BACK: Antetokounmpo had just returned from an eight-game injury absence last month, leading the Milwaukee Bucks to their third win in four games Giannis Antetokounmpo threw down the game-winning dunk with 4.7 seconds remaining to lift the Milwaukee Bucks to a 122-121 victory over the Charlotte Hornets and grab a slice of NBA history on Friday. The Bucks trailed by as many as 16 on their home floor, but Antetokounmpo scored 12 of his 30 points in the final quarter to help seal the win in a frantic finish that saw five lead changes in the final 45.7 seconds. The two-time NBA Most Valuable Player (MVP) added 10 rebounds and five assists. It was his 158th regular-season game with at least 30 points, 10 rebounds and
For the first time in almost 36 years, a Parisian derby will be played in French soccer’s top flight when reigning champions Paris Saint-Germain FC take on the nouveau riche Paris Football Club (PFC) today. Not one of the players involved in today’s match — PFC’s 38-year-old third-choice goalkeeper Remy Riou is almost certainly not going to be involved — was born the last time there was a Parisian derby in Ligue 1. That was on Feb. 25, 1990, when Moroccan midfielder Aziz Bouderbala scored a brace as Racing Paris 1 beat PSG 2-1 at the Parc des Princes home that
Stan Wawrinka’s 40-year-old legs did not let him down over three-plus hours in his first singles match of a farewell tour yesterday. Three-time Grand Slam singles champion Wawrinka beat Arthur Rinderknech of France, who is ranked 29th to Wawrinka’s 157th, 5-7, 7-6 (5), 7-6 (5). The match went 3 hours, 16 minutes. Wawrinka last month announced that this year would be his last on the ATP tour. “Today was a tough battle ... it’s amazing to come here for the first time, to have so much support,” Wawrinka said yesterday. “Twenty years on tour, you kind of always play in the same place
Manchester City have confirmed defender Josko Gvardiol suffered a broken leg in Sunday’s 1-1 draw with Chelsea at the Etihad Stadium. Gvardiol was one of two City centerbacks who went off injured in the second half, along with Ruben Dias, before Enzo Fernandez scored a stoppage-time equalizer for the visitors. The draw left second-placed City six points behind English Premier League leaders Arsenal. City, announcing Gvardiol sustained a tibial fracture to his right leg, added in a statement issued on Monday: “The defender will have surgery later this week and assessment remains ongoing to ascertain the full extent of the
