European football governing body UEFA has warned fans of Liverpool and Tottenham Hotspur that they are taking a major risk by attempting to secure tickets for the Champions League final in Madrid on June 1st from secondary ticketing websites.
Demand is unprecedented for the biggest club match in the world, to be held at the 68,000 capacity Wanda Metropolitano Stadium, the home of Atletico Madrid.
Many Irish supporters are fans of Liverpool and Spurs and plenty of them have booked travel and accommodation to Madrid without a match ticket in the hope of being lucky.
A UEFA spokesperson told Off the Ball: "We urge all fans not to buy from unauthorised points. The only system was either www.uefa.com for the general public or through the two club finalists, the real supporters of the two teams. That's it."
UEFA say they are actively seeking to void tickets purchased on resale sites.
"Yes, because they are not valid, these tickets, because they are not bought by authorised sources."
Tickets are going for a minimum of €5,495 on secondary site 'StubHub'.
Tottenham have already slapped 'indefinite bans' on three season ticket holders who tried to resell their tickets at inflated prices and Liverpool are investigating five supporters.
Face value tickets for the Champions League decider range between €70 for the cheapest and €600 for the most expensive.
Meanwhile, European football's governing body had 'no comment' to make when pressed on the issue of only half of the Arsenal and Chelsea's allocations being sold for the Europa League Final in Baku.
The decider in Azerbaijan next Wednesday is over 2 and a half thousand miles away from London, the home of both Premier League clubs.
The location has proved controversial enough, and now Armenian captain Henrikh Mkhitaryan and Arsenal have decided that it is not safe enough for the midfielder to travel due to political tensions between Armenia and Azerbaijan.
