For Cardoso, the high-stakes nature of the Champions League means the margin for error is razor-thin, and he believes referees deserve the best tools available to perform their jobs. He noted that the speed of elite football often exceeds what the naked eye can reliably track in real-time.
“Referees should be helped, the game becomes too quick nowadays, too much pressure, they need help, and this is a fantastic instrument to help the referees,” Cardoso said.
“Nothing against the referees, just supporting them so that they become better, like we [do]because we also [watch] videos. Everybody needs to get better and get help in the support, so yes important of course.”
