:INFO The Iberian derby, on the world's biggest stage Spain vs Portugal. Monday 6 July 2026, 3:00 PM ET. AT&T Stadium, Arlington, Texas. Capacity 80,000+. A spot in the World Cup 2026 quarter-finals is at stake, where the winner will meet Belgium or the United States. These two nations share the Iberian Peninsula, a common language family, centuries of rivalry, and 41 meetings in international football. They have never met at a World Cup. That changes on Monday. Spain arrive unbeaten, with a clean sheet in every match and a 35-game unbeaten run stretching back over two years. Portugal arrive on the back of a nervy extra-time win over Croatia, carried by a 41-year-old Cristiano Ronaldo who has scored three goals in this tournament and shows no sign of slowing down. One side goes home. One side goes to Boston for a quarter-final. Forty-one previous meetings have not produced a result like this one could. :STATS :THREAD :NOTE Lamine Yamal is 18 years old and already the most dangerous wide attacker at this tournament. He scored in the group stage against Austria and has registered two assists. In the 2023 Nations League, Yamal was not yet eligible to play. By the time the 2030 World Cup arrives, he will be 22. Portugal's left back, Nuno Mendes, is the only full back in this tournament ranked above him on WhoScored. This is the match-up that decides the game. :QUOTE [quotetype:plain, subtitle:Cristiano Ronaldo] I have never beaten Spain at a World Cup. There has not been a World Cup yet where we have played Spain. Monday is a first for both of us. :CHECKLIST Five things to watch at AT&T Stadium on Monday [ ] 1. Spain's high line: can Portugal's runners get in behind before the press wins the ball back? [ ] 2. Ronaldo in the penalty area: every corner and free kick is a chance. Portugal win 60% of set pieces. [ ] 3. Pedri vs Bruno Fernandes in midfield: the engine room. Whoever controls this zone controls the match. [ ] 4. Oyarzabal's movement: he drifts left, right, deep. Portugal's centre backs will have to choose. [ ] 5. The first goal: Spain have not been behind in this tournament. Martinez will want blood early. :NOTE The last time Spain and Portugal met in a knockout tournament, Portugal won on penalties in the 2025 UEFA Nations League final in Munich. Spain scored first through Fabián Ruiz; Portugal equalised through Joao Felix. The spot kicks were perfect until Dani Olmo missed Spain's fourth. Olmo is in the squad in Arlington. He will not be thinking about Munich. Or he will be thinking about nothing else. :LINK https://www.fifa.com/en/tournaments/mens/worldcup/canadamexicousa2026 Official FIFA World Cup 2026 site and live match centre
