Been overseas quite a bit in my time. These are the best stadiuns I have been to in order.
Cardiff Principality (formerly known as Millenium)
Wembley (new)
MCG
Wembley (old)
Marvel (formerly known as Etihad and Docklands)
Adelaide Oval
Lords Great Tradition but too small to be ranked above Australia's best cricket grounds.
Suncorp
Gabba
Twickenham (old).
Friends Arena in Stockholm
Parken in Copenhagen
Ullevi in Gothenbeg.
When i was in Brazillian i went to Maracaña stadium in Rio to watch Vasco V Flamenco, the greatest rivalry in brazillian football. It was fucking insane.
I went with a tour group from my hostel as it would have been too dangerous alone. Apparently the crowds can get completely out of control and riot, with people even being killed. Mental.
Anyway, we go to the game and there is riot police everywhere, armoured vehicles with water canons patrolling the streets, and a shitload of crazy fans. We finally found the way to our seats, and ordered some 0.2% alc/vol beer, which is all they allow inside the stadium.
Before the game started, it started pissing down rain, while lightning cracked in the distance.
From our seats we could see the Christ redeamer statue in the distance, with lightning lighting ip the sky around it. It was raining so hard that when the ball was kicked, it landed and stopped dead.
The atmosohere was insane!! The fans were separated, and they were playing massive drums and letting off flares everywhere. I have never seen anything like it.
I have also been to ANZ, the sydney showground, and the SFS. Hahaha
