If, at any time during the season, the UEFA administration deems that a venue may not be fit for staging matches of the season in question for whatever reason (including but not limited to pitch, facility and infrastructure, safety and security, operational and/or organisational problems), UEFA may consult with the host club/association concerned and ask them to propose an alternative venue, compliant with UEFA’s requirements, for all future matches of the season in question. Should a club/association not be able to propose an acceptable alternative venue by the deadline set by the UEFA administration, UEFA may select a neutral alternative venue. The club concerned will have to make all the necessary arrangements for the staging of some or all future match(es) of the season, in cooperation with the relevant association and local authorities. The costs of staging the match(es) are borne by the host club. The UEFA administration takes a final decision on alternative match venues in due time.
If any party to the match has any reason to doubt whether a match can take place as scheduled (including but not limited to pitch, facility and infrastructure, safety and security, operational and/or organisational problems), they must notify the UEFA administration immediately. If the UEFA administration receives any such notification, or has any reason itself to believe that a match may not be able to be played as scheduled, it decides if any change will be made to the venue, date and/or kick-off time. Such decision by the UEFA administration is final.
The referee decides if a match which has started must be suspended. This decision is made after consultation with the UEFA match delegate and, when possible, the UEFA administration.
