There's a road from Dortmund to Wembley? ... Pray tell?
Have you heard of Google map? They will give you a route of only 398 miles.
Dortmund airport only has a smallish terminal which is almost maxed out without football charters.
On the clubs website they state that they only have 24,000 tickets while 250,000 have applied for them in the first 24 hours. Up to 500,000 requests are expected to be made.
