Mexico vs South Africa

Mexico's recent form is strong (+1.03 pts/match vs expectations against decent opponents) while South Africa is underperforming (-1.10 pts/match vs weak opponents). The altitude at Estadio Azteca (2240 m) gives Mexico a significant acclimatization edge, as highlighted in recent news. Key player quality also favours Mexico, with multiple players at top European clubs versus South Africa's mostly domestic base. The model's 58% home win is too low given these factors; I raise it to 70%, with draw at 20% and away win at 10%. Mexico's expected goals are boosted by altitude and form, while South Africa's attack is weaker. The most likely scorelines reflect a 2-0 or 1-0 win for Mexico, with a 2-1 possibility if South Africa snatch a goal. Draws like 1-1 or 0-0 are less likely but still possible given South Africa's defensive organization.
