the fair odds for the draw should have been somewhere in the ball park of 5.000 - 10.000 shortly after the 4:0
Not sure that is enough. Its hard to look back, because when something
has happened its suddenly "possible" and almost "logical", human brain in its full glory. However, lets try to look back anyway:
What I do remember is that it was a competition game facing Germany away: this game actually was almost over at 1-0 after 10 minutes. Sure, you could think of a couple of lucky scenarios where sweden would shut them down and get a counter for 1-1. That could happen, but would have been a huge success.
Now, at 2-0 after 15 minutes, all you hope for is a swedish goal so you atleast get som contact and
excitement watching the rest of the game.
At 3-0 half time, it
was over. A lot of people stopped watching, even went home from the stadium. Now suddenly the "great" scenarios involved Germany slowing down, and Sweden getting a goal. 3-1 woudnt be embarrassing and atleast you could applaud a second half win, a goal scored in Berlin, etc.. The swedish fans would be pretty happy.
So before the second half, you hope this wont be too embarrassing. You dont want to go down 6 like Ireland.
At 4-0 then, you are in pain, because it points towards just that. "Just stop this flood!", thats your only thoughts if you are still watching. But even that looks impossible.
From there: a normal game, no scandals or weird things happening.
No, again, I believe this might be the strangest outcome in the last 100 years of fotball. Its not that it doesnt "make sense": its
impossible. Yet it happened, so while its not fun for Germany, this is great for fotball. Now there is no scenario where you cant think "but what if..?".
