RIO DE JANEIRO: The second round of the World Cup gets underway today with host nation Brazil facing Chile and Colombia taking on Uruguay in an all-South American race to reach the quarterfinals.

Brazil will be the first to play, in Belo Horizonte, and faces a Chile squad that has lived up to its pre-tournament expectations as a very good team that could cause few surprises.

Colombia, which plays an Uruguay lineup that will be missing Luis Suarez, has also delivered so far on predictions of being a potential quarterfinalist in Brazil. Given Suarez’s absence, Colombia’s run should continue after today’s game at Rio’s Maracana stadium.

What to watch today:

Brazil vs. Chile

The statistics point to one outcome at the Estadio Mineirao: Brazil has never lost to Chile on home soil and hasn’t been beaten by its South American rival in 14 years. On top of that, Neymar is already in scintillating form for Brazil at the tournament.

He scored twice in a labored 3-1 victory over Croatia in the tournament opener and struck two more to give Brazil a decisive 2-1 lead in what became a comfortable 4-1 win over Cameroon in its last group game.

However, Brazil’s players — and coach — are understandably wary of a dangerous Chile side, which has far less to lose than the hosts.

Chile’s 2-0 victory over 2010 World Cup champion Spain at the group stage underlined the potential of Jorge Sampaoli’s team, though a loss to the Netherlands by the same score maybe indicated its limits.

Venue: Belo Horizonte. Kickoff noon EDT.

Colombia vs. Uruguay

Things could hardly be going better for Colombia ahead of this match. Three straight victories and nine goals scored, playmaker James Rodriguez has been outstanding and now Uruguay’s best player, striker Luis Suarez, has been sent home.

Even allowing for the absence of its star forward, the injured Radamel Falcao, Colombia will be the favorite to reach the quarterfinals.

Rodriguez, who engineered the opening two victories over Greece and Ivory Coast but was rested for the first half of a 4-1 win over Japan, will return to the starting lineup.

For Uruguay, the loss of Suarez will be damaging — both technically and psychologically.

By contrast, strike partner Edinson Cavani has been in mediocre form so far at the tournament and will need to step up to the plate against Colombia.

Venue: Rio de Janeiro. Kickoff 5 p.m. EDT.
