Each participating association or club to which match tickets are allocated is responsible for ensuring that these tickets are allocated only among its own supporters.
When the match is played at a neutral venue, the match organiser is responsible for ensuring that none of its ticket allocation is passed on to supporters of the participating teams.
Match organisers and associations or clubs to which tickets have been allocated will be held entirely responsible if any tickets are found on the black market or in the hands of unauthorised individuals or agencies.
