Holders Chile face Peru in the semi-finals of the Copa America at the Gremio Arena in the early hours of Thursday morning.
La Roja were not expected to come close to defending the title they won in both 2015 and 2016, yet after a strong group stage showing Reinaldo Reina's side knocked out highly-fancied Colombia in the last eight.
Peru are also surprise semi-finalists after beating Uruguay in the quarter-finals, with La Blanquirroja making the last four despite winning just one of their four games in 90 minutes.
Chile are odds-on favourites against their northern neighbours with bet365 pricing them at 17/20 (1.85) to win in 90 minutes and at 2/5 (1.40) to qualify. Peru can be backed at 15/4 (4.75) with the draw available at 9/4 (3.25).
Peru are without forward Jefferson Farfan who is out of the tournament with a knee problem. Otherwise, neither side have any major injury issues heading into the game.
These two sides have a fierce rivalry, further stoked by Chile knocking out Peru out of the Copa America semi-finals four years ago.
Indeed, such is the ferocity of this fixture that the four of the last seven meetings have seen a red card and the price of 5/2 (3.50) for a sending off could be of interest.
In the previous round both of these sides were outsiders in their respective matches and with there being no extra time in the quarter-finals, it very much looked like both Peru and Chile played for penalties.
We are unlikely to see similar game-plans on Thursday, though, and this international derby tends to produce open and entertaining encounters.
Tips and predictions
Over 2.5 goals has paid out in each of the last five meetings, and in eight of the last nine clashes going further back. A repeat can be backed at 6/4 (2.50) which appeals as does the price of 6/5 (2.20) for both teams to score.
