Doesn't Brazil and Italy play matches where they don't score at all? You don't see that in many other sports. The results in soccer do have a large random element.
Lol, there's always the chance of a 0-0 but that scoreline is far more likely with teams that play long ball tactics. Brazil are probably the highest scoring team in the world and they always keep the ball on the ground and use lots of close control and passing, I can't think of a single successful long-ball team in the history of football.
As for random element? I can't see how it's more likely to be random than any other sport. Only 7 countries have every won the World Cup since 1930 despite hundreds entering, half of all of these trophies are shared between 2 teams.
I'm gonna take a punt here and guess there's no other sport in world where 2 teams have dominated in such brutal fashion
