Panos has a good point, as seat capaticance goes, i would be suprised if karaiskaki's stadium of 33,000 was in the top 100 of seat capaticance in europe, let alone the world. But it is a nice stadium by greek standereds, and the closeness to the pitch (which i've seen in pictures, i've never been) seems very close too the action... but its not one of the greatest stadiums in the world, by a long shot.
(Btw, this has not got alot to do with the stadiums, and alot of people may find this a little pointless... but do you realise if we had defeated liverpool in the 84-85 semi-final, the tragedy of heysel may never have happened, and all the laws of seating in stadiums may not even exist today, and our attendance would still be in the 40,000's??? a little something to think about)
