Morocco's fairy-tale run has everyone wondering if they can maintain their exceptional form. The Atlas Lions have outplayed both the Netherlands and Brazil, posting a 25-to-18 shot advantage across those matches while controlling roughly two-thirds of final-third possession. Their 0.24 expected goals allowed to the Dutch across 120 minutes showcases defensive solidity rarely seen from a team with just one true European star in Achraf Hakimi.

Paraguay presents a different puzzle entirely. They've made 718 low defensive actions through four games, far exceeding any other team's output. This defensive-minded approach works perfectly when they score first, as Türkiye and Germany discovered. However, falling behind early—as happened against the USMNT—exposes their vulnerability. Their counter-attacking style can frustrate anyone, but it's hard to envision them advancing deep if forced to chase matches.

Brazil's tactical uncertainty persists despite their comeback victory over Japan. While they dominated the second half with 11 shots and 80% final-third possession, the first half revealed familiar struggles. Carlo Ancelotti's side attempted 40 crosses—third most in World Cup history since 1960—but needed individual brilliance to overcome organized opposition. The question remains whether their talent alone can overcome tactical deficiencies against elite teams.

Canada's ceiling hinges entirely on Alphonso Davies' availability. The Canadian sensation reinjured his hamstring in May and has played just 22 minutes this summer. Jesse Marsch's squad combines aggressive pressing (top-10 PPDA) with rapid ball progression (1.85 meters per second—the fastest rate), but without Davies, they lack the game-breaking element needed to compete with football's elite. Their high-energy approach works only if their best player can stay on the pitch.
