Balls must comply with the IFAB Laws of the Game as well as with the UEFA Equipment Regulations.
For qualifying competition matches and training sessions, balls must be provided by the host association.
For matches and official training sessions during the final tournament, balls are supplied exclusively by UEFA.
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) is used in accordance with the IFAB Laws of the Game and the FIFA Quality Programme for Goal-Line Technology Testing Manual in all matches in the final tournament for the purpose of verifying whether a goal has been scored to support the referee’s decision. That decision remains under the sole discretion of the referee and is final.
If the host association of a qualifying competition match 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.
