Spain and Portugal will renew one of international football's fiercest rivalries on Monday when they meet in a blockbuster World Cup round-of-16 tie, with one of the tournament favourites guaranteed to make an early exit. Spain remain among the leading contenders for the title after a comfortable 3-0 victory over Austria.

The teams last met in the 2025 UEFA Nations League Final, when Portugal prevailed on penalties after a 2-2 draw. Portugal coach Roberto Martinez made the bold decision to replace Cristiano Ronaldo in the 82nd minute of his team's narrow last-32 win over Croatia, with substitute Goncalo Ramos scoring the decisive goal.
