This Saturday's World Cup action has a very South American flavour as hosts Brazil take on Chile, and an impressive Colombia facing a Uruguay missing a bite-sized bit of Luis Suarez.

BBC South American football expert Tim Vickery joined us on the line to preview and predict both games which are far from clear-cut.

He spoke about the way the pressure is cranking up on Brazil who have physically prepared to peak from this point of the tournament, why both games could be "tasty" and why the Brazil v Chile game will definitely not be cautious. 

He also explained why the final goal against Cameroon will raise optimism for Brazil manager Luiz Felipe Scolari for its collectivist quality.

Meanwhile, Tim also detailed how Colombia have historically had problems dealing with their own euphoria, and also highlighted Uruguay's perennial ability to dig deep.
