Portugal vs Spain: A preview of the World Cup Last 16
Portugal and Spain have now secured their spots in the World Cup’s Round of 16, with the match taking place on July 6th. Portugal advanced after an impressive 2-1 comeback against Croatia in the Round of 32, while Spain had a strong 3-0 win against Austria. So as it is, Portugal’s squad led by legendary striker Cristiano Ronaldo and supported by creative midfielders like Bruno Fernandes will be a formidable opponent against Spain’s younger squad consisting of Lamine Yamal and Dani Olmo, among others. Considering both teams’ strong lineup, it’s clear that this will be one of the most standout contests of the tournament.
In that light, Polymarket users can trade on event contracts like outrights, first to score, game to end on penalties, over/under goals, etc. It’s the kind of high-profile fixture that draws heavy volume across prediction markets, and this platform positions you to get into the action.
