Spain were viewed as one of the favorites to win the 2026 World Cup entering the tournament, and while it took them a bit to find their rhythm, they're fresh off their best match of the event – a dominant 2-0 win over France on Tuesday. Kylian Mbappe and France had no answers for Spain's defense, which shut the French team out and frustrated Mbappe and Co. all match long. Spain's next test is a doozy against Messi and Argentina, the defending champs. Argentina haven't looked like the best team this tournament ... that is, until late in matches. This Argentina team has a knack for late-game heroics, as they've scored 11 goals after the 75-minute mark. They beat England 2-1 in the semifinal with each of their goals coming after the 85-minute mark. Spain have far and away the best defense that Argentina has seen to this point, which could make those late heroics harder to come by. Argentina's defense has also been lackluster at times in recent matches, so we'll back Spain to win their first World Cup since 2010. 

Messi has a World Cup victory under his belt, but he doesn't have a Golden Boot. He has a great chance to take home that hardware on Sunday with a strong showing. Ultimately, this will be Messi's last World Cup match, and there's just no way the legendary striker doesn't find a goal in this big of a match, right? Even with Spain keying in on No. 10, Messi has a magical touch that perhaps no other player has ever had. He should end his career with a bang, even if Argentina fall short in the match as a whole.
