Manuel Neuer
This guy basically invented the modern goalkeeper role—instead of just hanging back in the goal, he actively leaves his line to sweep up loose balls and act like a sweeper on defense, which was revolutionary. He's widely considered one of the greatest shot-stoppers ever, with lightning-fast reflexes and incredible positioning that have made him a cornerstone of Germany's World Cup success. At this tournament, all eyes are on whether his aging body can still keep up with the speed of modern play, since he hasn't played as much lately. If you watch the match, keep an eye on how often he darts out of goal to grab the ball before strikers can get to it—it's the signature move that changed soccer forever.
