A Heartbreaking Conclusion for Croatia

In a dramatic turn of events during the Round of 32, Croatia appeared to have snatched a life-saving equalizer against Portugal in stoppage time, thanks to a goal from Joško Gvardiol. However, the celebrations were short-lived as a VAR review ultimately disallowed the score, cementing a 2-1 victory for Portugal and resulting in an early exit for the Croatian squad.


The Role of Connected Ball Technology

The turning point was not merely a subjective video review, but rather precise data provided by a microchip embedded within the match ball. Before Gvardiol found the net, Ivan Perišić delivered a cross into the penalty area, which reached Mario Pašalić. While the live action made it difficult to determine whether Igor Matanović had touched the ball before it reached Pašalić, the integrated sensor provided undeniable proof.

According to the sensor data, Matanović did indeed make contact with the ball via a flicking header. This proved critical for the offside ruling: while Pašalić was in an onside position when Perišić initially kicked the ball, he became offside at the exact moment Matanović touched it.


How the Technology Functions

The innovation used in the match is known as "Connected Ball Technology," developed by Adidas. The system operates as follows:

  • Technical Design: The chip is placed in one of the ball's four panels and uses inertia sensors to track movement.
  • Balance: Counterweights are added to ensure the ball maintains perfect balance during play.
  • Data Transmission: Information is sent to VAR officials in real time, assisting in the detection of ball contact, speed, and potential handball infractions.
  • Power Requirements: The chip is battery-operated and requires recharging before matches, with a battery life spanning approximately six hours.

Looking Ahead

Croatia has become one of the first teams to see a goal overturned based on direct input from this advanced chip technology. With this victory confirmed, Portugal is set to advance to the Round of 16, where they will face Spain this coming Monday.
