Portugal were simply in a different class. Roberto Martínez deployed a 4-3-3 that maximised width — Leão and Bernardo Silva pinning back DR Congo's full-backs — while Vitinha and João Neves provided the engine room to dominate the midfield battle. The key tactical wrinkle was Nuno Mendes operating almost as a second winger in possession, overloading the left channel and creating the conditions for the second goal. DR Congo's 4-4-2 was compact but too passive; they invited pressure and were eventually overwhelmed by Portugal's combination play in tight spaces. The penalty was the match's turning point — Mbemba's rash challenge on a yellow card gifted Ronaldo an iconic moment and deflated any Congolese belief. Portugal's substitutions were astute: Ramos added a direct goal threat and scored immediately, while Fernandes' set-piece quality proved decisive for the fourth. The only mild concern for Portugal is the midfield yellow for Rúben Neves, who will need to be cautious in the next group game. Overall, a near-perfect Group K debut.

• Portugal's xG of 3.71 was their highest in a World Cup group-stage opener since 2006 — a statement of attacking intent.
• Cristiano Ronaldo became the first player to score in six different FIFA World Cups, netting his 10th World Cup goal overall.
• Rafael Leão completed 5 dribbles — the most by any player on the pitch — and created 3 chances in just 70 minutes.
• DR Congo managed just 1 shot on target across 90 minutes, underlining Portugal's defensive solidity (0 errors leading to shots).
• Bernardo Silva's through-ball for Ramos registered as the highest xA (0.62) of any single pass in the match.
• Portugal's 67% possession was their highest in a World Cup match since the 2022 group stage against Uruguay.
• Gonçalo Ramos scored with his first touch after coming on — his third substitute goal in major tournament football.
