why are football matches “at home” or as “visitors” treated like an advantage or disadvantage?

Question

is there any way in which this fact could affect a match by itself?

Answer 1

At least in South America, playing visitor can be a living hell, specially if it’s a high stakes game like a clásico (derby) or a Copa Libertadores (our third world Champions League) match. It’s not uncommon for the visitor team to be pelted with trash or rocks from the stands, having power or water shortages on their lockers, or having fans from the local teams making noise outside the hotel the night before the match.
