Is Defensive Football Just Way More Viable and Effective, Or Was Germany Not That Good????

I can't wrap my head around what happened to Germany... it's not like they were not trying, i mean they actually did score a second goal that was disallowed.

Yes i salute the Paraguay squad... no doubt. They defended like champions.

But they really just parked the bus. Maybe this the best strategy in football right now?

Can someone with tactical knowledge give us a rundown of why Germany lost?

Thank you
