A card-happy referee and a dubious goal (offside) do nothing to change what is ultimately a fair result.
Credit to the Chileans who kept pouring forward even after scoring what turned out to be the game winner. They could've retreated defensively and attempted to protect their advantage; instead they lashed the Swiss with wave after wave of continuous strikes.
Depending on the results of the remaining 3 matches in the group (Honduras-Spain, Chile-Spain and Honduras-Switzerland) Chile may come to regret all their missed chances if goal difference comes into play
