With contrasting paths into the FIFA World Cup round of 16, which side will come out on top in the Iberian Derby? Look ahead to Monday’s must-see tie with our Portugal vs Spain prediction and preview.
Portugal vs Spain: The Key Insights
Spain are once again favourites ahead of kick-off, with the Opta supercomputer giving them a 49.2% win probability to Portugal’s 25.6%. Portugal have won just one of their 12 competitive meetings with Spain across competitions (D6 L5) – a 1-0 victory in the group stages of the 2004 European Championship. La Roja are yet to concede a goal in this year’s tournament, keeping clean sheets in their opening four matches of a World Cup campaign for the very first time.Two pre-tournament favourites will meet in one of the standout World Cup round-of-16 ties when Portugal face Spain in the Dallas heat on Monday.
Roberto Martinez’s side scraped through the round of 32 by the barest of margins, needing both a stoppage-time goal from Mikel Oyarzabal double and a Pedro Porro strike.
Having also kept Morocco scoreless before their penalty-shootout exit in the round of 16 in 2022, Spain could become the first side in World Cup history to keep six successive clean sheets if they shut out Portugal.
Ahead of kick-off, Luis de la Fuente’s side are predicted as heavy favourites, and for good reason.
La Roja are unbeaten in their last 34 matches (W25 D9), one shy of equalling their longest-ever unbeaten run of 35 set between February 2007 and June 2009. Only Italy, with 37 between 2018 and 2021, have enjoyed a longer unbeaten run among European nations.
Much of that success has come under De la Fuente, who is unbeaten across his first 11 matches at either the World Cup or Euros (W10 D1), conceding just four goals.
Should Spain overcome Portugal in Dallas, the Spaniard would join Aimé Jacquet and Louis van Gaal as the only managers to avoid defeat across each of their first 12 major international tournament matches.
Spain’s dominance has also extended well beyond their results. They have posted an average expected goals (xG) difference of +1.80 per game at this World Cup (2.0 for, 0.2 against) – the best by any European nation to progress beyond the group stage since France averaged +1.82 in 1998.
Portugal, meanwhile, are averaging an impressive 1.6 xG per game of their own this tournament – their highest figure since averaging 1.7 in 2014 in Brazil.
If they are to finally end Spain’s unbeaten run, Martinez will certainly need Ronaldo at his clinical best. The Portugal captain has scored four goals against Spain – the joint-most of any player alongside Eduardo Vargas.
Spain, though, have their own in-form forward in Oyarzabal. His four goals at this year’s World Cup are already the most by a Spain player in a single edition since David Villa scored five in 2010, when La Roja lifted their maiden World Cup trophy.
Portugal vs Spain Head-to-Head
There has been little to separate Portugal and Spain across their five previous meetings at major tournaments, with each side winning once and the remaining three ending in draws.
That includes their most recent World Cup meeting, a 3-3 draw in 2018 in which Ronaldo scored a sublime hat-trick, and their last knockout clash, a goalless draw in the semi-finals of UEFA Euro 2012 before Spain progressed on penalties.
Portugal, however, have won just one of their last 12 competitive meetings with Spain (D6 L5), that 1-0 victory coming more than 20 years ago in the group stages of the 2004 Euros, courtesy of Nuno Gomes.
But they will take confidence from having defeated Spain, albeit in a shootout, in their most recent meeting in the Nations League final in June 2025.
Portugal vs Spain Prediction
The Opta supercomputer struggled to look past Spain progressing to the quarter-finals, with De la Fuente’s side winning inside 90 minutes in 49.2% of the 25,000 pre-match simulations.
Portugal, however, will be full of confidence after narrowly defeating Croatia and will want to make every chance count, with their odds currently placed at 25.6%, while a draw (which would mean extra-time and maybe penalties) accounts for the remaining 25.2%.
