Been to the stadium twice with England, looks a lot bigger than the 50k plus capacity it has. Looks huge from the outside.
Been to the ArenA once before at an away game with what was my local club back then. There used to be what is basically a huge moat around the field: https://www.gogmeunited.nl/grachten-arena/ It looks so much better these days, but even back then it was impressive to much younger me being used to a stadium that would hold 11k people at full capacity. And we managed to hold our for a draw which we rightfully celebrated as if we'd won!
