Colombia will take on Brazil on Friday evening with a place in the World Cup semi-final at stake.
Los Cafeteros come into the tie as the form side, but they will also be aware that history is not in their favour.
Colombia have won just five of 35 fixtures between the two sides, while it is 23 years since their last triumph. Brazil, on home soil, are formidable opponents.
To succeed, Colombia will need to win key individual battles right across the pitch in order to put themselves on the front foot.
The question is, then, upon which confrontations the clash will be determined?
