Dejan Kulusevski
This Swedish midfielder is basically your team's Swiss Army knife—he can play multiple positions, runs like he's got rocket boosters, and isn't afraid to mix it up physically. At this World Cup, he's one of Sweden's most important creative players, meaning he's the guy who sets up goals and keeps his team's attack moving forward. What you should watch for: his ability to suddenly burst down the wing and whip the ball into dangerous areas, plus his tireless work rate that makes him valuable even when he's not scoring. He's the kind of player that casual fans often overlook until you realize he's involved in almost everything his team does well.
