For the preliminary round, round 1 and round 2, balls must comply with the IFAB Laws of the Game as well as with the UEFA Equipment Regulations. The home club must provide the visiting club with match balls of excellent quality for its training session on the day before the match as well as for warming up before the match. These match balls must be the same as those used for the match.
The applicable official UEFA match ball determined by the UEFA administration must be used for all matches from the group stage and for the official training sessions before these matches.
The UEFA Women's Champions League centre board must be installed at all matches as from the group stage. Further details on the centre board and the rules applicable to its production, position, installation and visibility are set out in the UEFA Women's Champions League Club Manual.
The use of two-sided substitution boards (preferably electronic) is compulsory.
For each match up to round 2 (inclusive), the host club must ensure that two substitution boards are available.
Goal-line technology (GLT) may be used in accordance with the IFAB Laws of the Game and the FIFA Quality Programme for Goal-Line Technology Testing Manual as decided by UEFA, or in accordance with Paragraph 37.07 for the purpose of verifying whether a goal has been scored to support the referee’s decision. That decision remains at the sole discretion of the referee and is final. UEFA may decide to use GLT in certain matches.
If the home club has a FIFA certified GLT system at the stadium and wishes to use it for the match, it must obtain the visiting club’s consent and UEFA’s approval via the official GLT approval process communicated by UEFA. The home club then contracts the approved GLT service provider directly and bears all the associated costs. The entire approval and contracting process must be completed at least 30 days before the match is scheduled to take place.
A failure of the GLT system may in no way prejudice the decision of the referee. If necessary, for example in case of a system failure, matches will take place or continue without the use of GLT.
Pre-installed GLT systems may be used in rounds 1 and 2, subject to UEFA's approval and the visiting club's consent. The host club remains fully responsible for the system and bears all associated costs.
As of the group stage, pre-installed and certified GLT systems may be used, subject to UEFA's approval. If such a system is used, it may only be used starting from the club's first match of the group stage or, alternatively, starting from its first match of the knockout stage. From that point on, the system must be used for all matches played by the club in the competition. The host club remains fully responsible for the operation of the system and bears all associated costs.
