Scotland and Brazil have never met at a World Cup. That changes on Wednesday night at Hard Rock Stadium in Miami, and the timing could hardly be more loaded for both sides.
Group C goes into its final round with Brazil and Morocco level on four points apiece, Scotland a point behind on three, and Haiti already eliminated. A win for Scotland sends them through regardless of what happens elsewhere. A draw may not be enough, depending on Morocco's result against Haiti. Defeat ends their tournament. The equation is brutal and simple.
Brazil, for their part, are not here merely to see out the group. A draw would confirm their progress but top spot is still contested, and a loss to Scotland would open the door for Morocco to leapfrog them. The Selecão have four goals from two games, the best attacking return in Group C, and have not lost a match. Coasting, for a side of their ambitions, is not really an option.
Scotland's route to this point has been characterised by efficiency rather than adventure. Three points from two games, a single goal scored and one conceded, suggests a side that has made the very most of limited resources and asked little of fortune. They have already outperformed most pre-tournament expectations simply by arriving at matchday three with their fate in their own hands.
Neither squad reports any fresh injury absences ahead of kick-off, which at least gives both managers the luxury of selection without disruption.
The head-to-head record offers nothing to go on. These two nations have not faced each other before, so there is no precedent to weight, no psychological scar tissue on either side. It is, as cleanly as these things ever are, a fresh contest.
The data leans against the Scots, but not devastatingly so. Prediction models give Scotland a ten per cent chance of victory, with the draw and a Brazil win each sitting at 45 per cent. The advised combination covers a draw or Brazil win alongside a low-scoring game, which points to a tight, cautious match rather than an open one. Scotland will not mind that framing. If they are to cause one of the tournament's larger upsets, limiting Brazil's space and staying in the game deep into the second half is precisely the kind of football that gives them a chance. The data expects Brazil to advance. Scotland's entire tournament has been built on ignoring that kind of expectation.
