It is counter-intuitive because it contradicts the notion of consistent quality and performance.
Team A decisively beats Team B decisively beats Team C but Team C somehow comprehensively beats Team A, completing the full round of mutual merking.
Gooner 1: I thought Arsenal was going to lose to Man City, because Man City destroyed Man United 6-1 and Man United destroyed Arsenal 8-2. But Arsenal actually just obliterated Man City 4-0!
Gooner 2: Hell yeah for the circle merk! GO ARSENAL!
