The Danish FA has warned that Irish fans who bought tickets for the Danish section of Parken Stadium face the risk of being turned away.
Irish fans snapped up the 2,400 away tickets available, but some may try to overcome this by buying tickets in the home end of the 38,000 capacity stadium in Copenhagen.
Danish Football Union (DBU) communications director Jacob Wadland spoke to Morning Ireland about the situation, and advised that any Irish fans who manage to beat the system should “stay quiet and take off the green jersey”.
“There’s always a chance they they may get in, and maybe they won’t cause concern,” he said.
“But what we are concerned about is, should Ireland, heaven forbid, win the game or score two or three goals, we would try to avoid the situation where a group of Irish fans are jumping up and down and happy and sitting in the middle of 500 Danish fans, who are annoyed.
“That creates tension and that’s what we’re trying to avoid.
“If they are capable of beating the security, stay quiet and take off the green jersey.”
“There could very well be some who have tried to ignore the warnings we have given and tried to buy tickets in the Danish section.
“We are required by UEFA and FIFA to make sure that Danish and Irish fans are segregated.”
“To buy a ticket you would need to have provided a Danish mobile phone number, you would need to have paid with a credit card that is not issued in Ireland. Those who have done so stand a chance of being rejected when they come to the stadium, that’s for sure.
“They would stand the chance that when they try to enter the stadium, the tickets would not be valid, they would be stopped at the entrance.”
