Video assistant refereeing (VAR) and goal-line technology (GLT) may be used in accordance with the IFAB Laws of the Game for the purpose of assisting the referee.
No sources or systems other than the official VAR system may be used by the referee to review replays during the match.
VAR may be used in any and all matches of the competition. The decision as to whether VAR should be used for a specific match is at the sole discretion of the referee, and that decision is final. The non-use of VAR for part or all of the match, whether due to the referee's decision or technical failure or unavailability, in no way prejudices the validity of the referee's decisions, which are final in all cases.
GLT is used in all matches of the finals to help the referee determine whether a goal has been scored. The referee's decision is final in all cases.
In the event of technical failure, matches may take place or continue without the use of GLT. The non-use of GLT in no way prejudices the referee's decisions, which are final in all cases.
