Our top picks for the Spain vs Belgium showdown
Multiple options are available for Spain vs Belgium games at Polymarket. But based on the pedigree and form of these two teams, our experts are leaning into these picks:
Team to Advance – Spain
8th-ranked Belgium is undeniably one of the best national soccer teams in the world, and they’ve proved their quality, most recently dispatching co-hosts USA in a dominant 4-1 display. However, Spain have been among the top World Cup contenders in consecutive competitions, and are among the top three likely to win this year. After sending home the legendary Cristiano Ronaldo and Portugal in a hard-fought 1-0 win, we expect them to see off the Red Devils as well. It’s worth noting that the result of this market covers Extra Time and penalties. It’s decided by whoever goes through to the semi-finals.
As we head deeper into the knockouts, extra time is one of the more popular sports prediction markets for the World Cup. Basically, when two teams are level after the standard 90 minutes allotted (regulation time), they get to play another 30 minutes of extra time split into two 15-minute halves. Difficult matchups tend to go into extra time (all the way into penalties even). And with the stakes at the quarterfinal level, there’s a good chance both Rudi Garcia’s and Luis de la Fuente’s men will drag it out to the end.
Totals – Under 3.5 Goals
Since the Group stages, Spain and Belgium have scored a lot of goals against less challenging teams. It’s a different story when faced with stronger opponents. Given the pedigree of both sides, this is likely to be a difficult clash that doesn’t produce too many goals. Under 3.5 is a fair call.
