Mexico holds a trader consensus of 48% implied probability to top Group A, driven by co-host advantages including two home matches at high-altitude Estadio Azteca and Estadio Monterrey, where acclimation challenges favor El Tri's familiarity and recent 4-0 friendly win over Iceland. Czechia jumped to 26.5% after their dramatic March 31 penalty shootout qualification over Denmark (2-2, 3-1 pens), building momentum with midfield anchors Tomas Soucek and forwards Patrik Schick and Adam Hlozek in strong form. South Korea lags at 20.5% despite Son Heung-min's quality, stung by a 0-4 friendly loss to Ivory Coast exposing defensive vulnerabilities ahead of altitude tests. South Africa trails at 6.2%, banking on goalkeeper Ronwen Williams' shot-stopping but facing steep odds in this balanced group stage draw.
