VAR and 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 the final (both legs). In addition, UEFA may decide to use VARs in other matches as well. 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. In the event of technical failure, matches may take place or continue without the use of VAR. 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.
If GLT is used in line with Paragraph 33.04 and in the event of technical failure, matches may take place or continue without the use of GLT. The non-use of GLT 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.
