The Germans are coming, the Germans are coming

Wembley, 2013. The champions league final between Bayern Munich and Borussia Dortmund.
All the money that went into the new wembley and we couldn't manage an all English Final.
 Even better, an all London Final.
Chelsea v Arsenal.
Arsene Wenger and Rafa Benitez have come up with a master plan.
They have got Captain Mainwairing and the rest of the Home Guard of Dads Army to solve the problem.
Corporal  Jones and the rest of the lads are going to remove all the road signs so that no roads lead to Wembley.
The Germans will end up somewhere in the Welsh mountains.
Sepp  Blatter could investigate as to how the Champions league final had to go ahead with two London teams because the TV cameras were ready to roll.
"Right we want to find out who did this? What is your name?"
"Don't tell him Mata"
"Private Mata."
