Here is the quote from cyber-soccer.net

"I have just had word back from Nick Grange of the UK EA Sports PR department. I asked him about the lack of stadium selection in FIFA 2000. He said that there is no select option as there are no real stadiums in the game! Now I'm sure we were all led to believe that there were real stadiums in the game, but here is the real truth!"

I believe that for sure today I was playing in a stadium that was in some ways like San Siro but not quite... Still stadiums and how they look, it doesn't matter to me really.
