Colombia need maximum points here and results to go their way. Díaz against Portugal's backline is the most evenly matched individual duel in Group K MD3 — if Colombia can get him into 1v1 situations, they create genuine danger.
James Rodríguez's set piece delivery gives Colombia a set piece advantage — Portugal's defense against corners has been a recurring vulnerability.
Portugal almost certainly arrive qualified as group winners. Martínez will give Ronaldo and Bernardo Silva a rest — Gonçalo Ramos and Vitinha starting in their places.
Even a rotated Portugal has the technical quality to control a match. Their pressing system under Martínez doesn't depend on individual stars — the structure wins even with B-teamers.
Portugal lead 3–1 all-time. No prior World Cup meeting.
