When I have been to the game v. Bayern to Nou Camp ( + Later I took the tour of the stadium and museum ) my impression was really great and WTF would we need so big renovations?
But I paid 64 euro for a ticket under the roof so I didn't get to see the entrances to the other parts of the stadium, saw a video though and I gotta say it kinda looks like a parking lot on the opposite side.
Even in this situation, I would actually promote a non-Allianz type cover that makes me a bit sick ( even though our project isn't that bad ) it still looks like a toilet seat and thats why I love stadiums from the last century, design more original for each one, more steep stands ( See Mestalla v. Nou Mestalla / Highbury v. Lowbury *pardon* Emirates etc ). Of course Bayern needed a new stadium with no track, we will keep you stands but I still think a more rare design can be found. Maybe it's just because I realise that the NOU CAMP that I know since the beginning won't be the same again!
