Things look to be headed this way:
Spain and Uruguay to go trough to semis in that order (unless Nigeria beats Spain, then depending on the Tahiti Uruguay scoreline, Nigeria could go trough, but this is unlikely)
Brazil and Italy already in semis, order pending on the match between them
Semis as follows, IF Brazil wins or ties with Italy:
Spain-Italy
Brazil-Uruguay
Side note: Uruguay is infinitely less powerful than Spain, so i bet both Italy and Brazil want to avoid them, but...
Uruguay has a soft spot for knocking out host nations, and we have a long tradition on doing so, staring in 1916.
Copa America 1916 Argentina, knocking out Argentina to become champions
Copa America 1920 Chile, knocking out Chile to become champions
Copa America 1926 Chile, again knocking out Chile to become champions
Copa America 1935 Peru, beating Peru to become champions
Copa America 1959 Ecuador, beating Ecuador to become CHampions
Copa America 1983 beating Brazil in Brazil to become champions
Copa America 1987 in Argentina beating Argentina to become champions
Copa America 2011 in ARgentina, again knocking out the hosts to become champions
World Cup 1950 in Brazil, beating Brazil to become Champions
Olympic games 1924 in France, beating the French to become Champions
Olympic games 1928 in Holland, beating the dutch to become Champions
The above only reflects the situations where Uruguay effectivly went on to win the championship, and does not include situations where we beat the host nation but didnt win it all (i.e South Africa 2010)
We are lousy guests
even when our squads are effectively weaker. Only god knows how we do it
