The cancellation of Croatia's killer goal against Portugal in injury time sparked controversy among fans during the World Cup, with many questioning the decision made by the match referee.
Josko Gvardiol scored a goal in the final seconds of injury time, which the referee counted amid some objections from the Portuguese players, who were in shock due to conceding the equalizing goal.
Television replays showed Mario Pasalic, the goal creator, in an offside position when receiving the ball after a header from his teammate Igor Matanovic.
The situation was not that simple, as the video assistant referees (VAR) had to call the on-field referee to review the footage due to the new technological advancements in the World Cup, most notably the "smart ball."
Igor Matanovic slightly touched the ball with his head, and although the image was not clear, the "sensor" technology inside the World Cup ball made the referee's decision easy.
