To be honest...no.
If you're going to a football match and you find out you've got to travel to West London instead of North London, you ain't going to suddenly need child care and an extra day off work...London ain't that big!
I know that if you're going to the game regardless it doesn't make much of a difference. I was referring to people who wouldn't go to the game at Wembley but would if it were at the new stadium.
