Europe is the largest and the third largest in the world. I know nothing... From the perspective of pedestrian experience: 1. Too big, ticket office can not be found at once, the entrance is also confused for three seconds, even if the entrance is behind. 2. Have student discount, praise. 26.5 euros to 21.5 euros. 3. Like Real Madrid, voice guides cost money. 4. First take three sets of photos, then see a pile of trophies. Then there are the stadium, some trophies and pictures, and some pictures and texts. And then exports. Poor guidance, although very large, but the visual and auditory impact is not as good as the Real Madrid Stadium. 5. Export can take fast photos, three into a book, 39 euros, thieves expensive... A sheet of 20 euros... Thieves are expensive [not simple] [not simple] and walk down as a whole. Passers-by are not meant to be non-flammable...
