Might be a little more difficult to get tickets outside if the stadium this time Bundesbiers but 149 Euros for a Cologne standing area ticket is way too much money though its the FC "Fanblock".
I guess face value of the ticket is roundabout 20 Euros.
On the other hand - I paid 280 USD for a Packers ticket at Lamebau field with face values of roundabout 80
Euros
But I didnt want to travel across the globe to end up in front of Lambeau Field and not getting in to see the game
What I want to say is - I might be tempted to buy the 149 Euros ticket for this very special game if I were you
