Balls must comply with the IFAB Laws of the Game as well as with the UEFA Equipment Regulations.
For qualifying competition matches, as well as for training sessions, balls of excellent quality must be provided by the host association. The balls provided for training must be of the same type and quality as those used for the matches.
The use of two-sided substitution boards (preferably electronic) is compulsory for all matches. For each match a minimum of two boards must be provided by the host association.
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 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.
If the host association of a match in the qualifying competition has a certified GLT system at the stadium and wishes to use it for the match, it must obtain the visiting team’s consent and UEFA’s approval via the official GLT approval process communicated by UEFA. The host association 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.
