Portugal vs Spain in the World Cup round of 16 kicks off at 3pm Eastern on Monday, July 6, at AT&T Stadium in Arlington, Texas.

The winner takes a quarterfinal place. Bet365 lists Spain at -111 to win in normal time, the draw at +250 and Portugal at +300.

Spain arrive unbeaten with no goals conceded

Spain won Group H and have not conceded in four matches at this tournament. They beat Saudi Arabia 4-0, edged Uruguay 1-0 and dispatched Austria 3-0 in the round of 32.

Mikel Oyarzabal scored twice in that Austria win, and Pedro Porro added the third. Eight goals scored, none allowed. The defence, more than the attack, has been the quiet story of Spain’s tournament.

A late escape kept Portugal’s run alive

Portugal needed a comeback to get past Croatia in the last 32. Cristiano Ronaldo converted a penalty, then Goncalo Ramos headed the winner in added time.

An escape like that can settle a squad. Portugal also bring recent history into this fixture. The last meeting came at the UEFA Nations League Finals in 2025, when Portugal beat Spain on penalties.

What decides Monday’s match in Arlington

Spain enter as favourites, and their record this tournament supports it. No side has looked more controlled through four games.

Portugal’s case rests on knockout nerve. They have already won late once, and they beat this opponent in their last meeting. They also have Ronaldo for the big moment. Spain have not trailed yet, so the first goal on Monday may matter more than usual.

The winner moves into a quarterfinal later this week. The loser starts a long summer.
