Morocco arrive at Mercedes-Benz Stadium on Wednesday night knowing a point will almost certainly be enough to see them through to the knockout rounds, but Walid Regragui's side will be well aware that football has a habit of punishing complacency at precisely the wrong moment.
Group C has tightened considerably heading into the final round of fixtures. Morocco sit second on four points, level with Brazil at the top, having won one and drawn one from their opening two games. Scotland, on three points, are very much alive. Haiti, meanwhile, are bottom with nothing from nothing: two played, two lost, four conceded, and the tournament's cruellest arithmetic now requiring them to beat Morocco while hoping other results go their way. In practice, Haiti need a minor miracle. In practice, that is exactly the kind of match that occasionally produces one.
There is no head-to-head history between these two sides to lean on. They have simply never met at this level before, which removes the comfort of precedent for both camps. For Morocco, that means no inherited psychological edge. For Haiti, it means no inherited psychological scar either.
Team news offers little drama. Both squads report no fresh absences ahead of kick-off, which means Morocco can select from full strength and Haiti's coaching staff have no enforced changes to navigate. A clean bill of health is, at least, one small mercy for a Haitian side that has had precious little to celebrate in Atlanta so far.
Morocco have conceded just once in this tournament and kept a clean sheet in their draw, which suggests a defensive organisation that does not buckle easily. Haiti have yet to score, which means everything about this match points in one direction tactically: Morocco will be content to control possession and tempo, while Haiti must somehow force them into errors they have shown little inclination to make.
The data leans heavily in Morocco's favour, with the prediction model placing Morocco and the draw at equal probability, each at 50 per cent, and Haiti's chances of winning at zero per cent. That reflects the gap in class and circumstance. A low-scoring Moroccan win or a careful draw are the scenarios the numbers point towards, which suits Morocco perfectly well, even if it makes for a tense evening in the stands.
Kick-off is at 23:00 UK time on Wednesday 24 June.
