From the post today:
Last night AC Milan promising every one of its season ticket holders the chance to reserve a ticket for the final. Their website claimed: "If you have followed Milan for the entire season at the San Siro, then you absolutely will not be left out of the most important date of the season, the champions league final in Athens!"
Although the site states that there are more season ticket holders than there are tickets to the final, the club simply says that "fans that are the most loyal will be given priority".
