Spain to win in regulation ($0.43)
Argentina have had a magical run to get back to the final. Their time in the knockouts has been filled with late goals and no shortage of Messi magic. Unfortunately, the ride is likely over. Spain are too defensively disciplined to make the same mistakes as foes like Egypt, Switzerland and, yes, England. Spain won't curl up and let Messi do whatever he wants with the ball after taking a lead like England did. This will be a tightly contested match and the Spaniards may not keep a clean sheet, but the winners will likely be wearing red.

Lionel Messi 1+ goals: ($0.36)
Everything that we just said about Spain's excellent defense is true. They've allowed just one goal over the course of the tournament. They earned a clean sheet against Kylian Mbappe and France. This is one of the best defensive teams ever, but Messi is Messi, and he excels on the biggest stages. The GOAT should find a way to beat Unai Simon at least once before all is said and done, even if Argentina don't retain the title.
