The FIFA World Cup 2026 kicks off at a stadium in Mexico City today in what could be the most high-tech edition of the tournament yet. Every team will have access to an artificial-intelligence tool that can analyse its players’ movements, and digital avatars of the players, created from scans of their bodies, will help referees to model match action and spot illegal moves.
AI and Euro 2024: VAR is shaking up football — and it’s not going away
To understand the role science will have in football’s biggest tournament and where the field is heading, Nature spoke to the editor-in-chief of the journal Science and Medicine in Football, which publishes research on various forms of football, including association football — also known as soccer — American football and rugby. Franco Impellizzeri, also a sports scientist at the University of Technology Sydney in Australia, once competed for Italy’s national taekwondo team. But he admires football — “I’m Italian, so football is part of our culture” — and has since collaborated on studies with football organizations including FIFA (the International Federation of Association Football) and elite clubs.
He says that AI has led to a surge in football research, which he can see in journal submissions, but that until scientists work out how best to handle the data deluge, “an increase in quantity doesn’t always come with a similar increase in quality”.
How will science play a part at this World Cup?
FIFA has regularly introduced various technologies to improve the fan experience. For this edition, they have announced the use of AI-generated 3D avatars.
There are also new systems to help referees make decisions, including detecting offsides and handball touches. The latter is made possible by using smart balls with sensors inside them.
There is also a real-time system to provide staff with match analytics: information on how players move on the pitch, tactical behaviour and individual behaviours of the players. Since these systems are provided by FIFA, it is a great way to democratize access to technology. Whether the teams will have people on their staff who can actually use this information is another question.
