I would not trsut the german fans during the EU 2004. Simply because Germany will be gone after loosing 3 games. The team is so crappy.
I wouldn’t classify them as crappy. With the exception of the final game, they looked pretty good in the World Cup.
I can not recommend wearing a Dutch shirt when watching the game in Germany.
I will take that advice and leave the Dutch jersey in the hotel room. I will bust it out when I get to Portugal, and when I watch them play Latvia in Bragga.
