I mean the biggest individual stand not stadium and it doesn't count if it is just a random section of a bowl that they are pretending is a separate stand like they do at the keepmoat
Apparently that's the largest in Europe which means there is at least one bigger somewhere else but I can't find anything saying which one. However despite every site I can find saying that the yellow wall is the biggest at 25000 the sir Alex stand at old Trafford actually holds 25500
The North Stand at Celtic Park apparently holds over 26,000 seats and therefore is the biggest in Britain. Old Trafford North Stand is the second largest. No idea about the rest of the world, I'm guessing the side stand of the Nou Camp will be the biggest, although whether it's actually a 'stand' or part of the 'bowl' is open to debate.
Waiting for a Bovril in the East Stand upper whilst the 12 year olds struggle with the concept of "service" Lots of standing involved Trying to get out of the car park before midnight (ok you can sit) Trying to take back an ORA shirt to the club shop when it says L but in fact it is the L version of a Brazilian Pygmy tribe (Huge amount of standing involved)
