Tickets for Euro 2012 went on sale today but Republic of Ireland fans face a two-month wait before they will know if they have been successful.

The tickets went on sale on but are not a first-come, first-served basis and the application window will remain open until the end of February.

Tickets for Irish fans are restricted to official fans groups, with special log-ins being supplied by the FAI.

In the event of the matches being over-subscribed then ballots will be held with the most loyal fans getting preference.

Irish supporters will also struggle to buy tickets allocated for Spain, Italy and Croatia fans, as they are only available to nationals or residents of those countries.

UEFA said 32% of the overall stadia capacity have been reserved for the supporters of the 16 finalists.

A UEFA statement said: "Each team will receive 16% of the overall net stadium capacity, or a minimum of 6,000 tickets, for each of their group-stage match. For quarter-finals and semi-finals, the number of tickets reserved is 5,000 per participating team, and for the final it is 9,000 per participating team."
