The FIFA tie-breaker, or any goal-differential scheme, can cause problems, too. There have been incidents (especially in basketball) where players on a favored team have won the game but deliberately ensured the quoted point spread was not covered (see point shaving). Conversely, there are cases where a team not only lost (which might be honest) but lost by some large amount, perhaps to ensure a point spread was covered, or to grant some non-gambling related favor to the victor. Perhaps the most famous alleged example was the match between Argentina and Peru in the 1978 FIFA World Cup. Argentina needed a four-goal victory to advance over Brazil, a large margin at this level of competition. Yet Argentina won 6–0. Much was made over political collusion, that the Peruvian goalkeeper was born in Argentina, and that Peru was dependent on Argentinian grain shipments, but nothing was ever proven.
