Ivan Perišić
This Croatian winger is basically the team's Swiss Army knife—he can play multiple positions and is dangerous at both ends of the field, which is rare for a wide player. He's been one of Croatia's most consistent performers at major tournaments, and at this World Cup he's crucial because the team relies heavily on creative attacking play from the wings. What casual fans should watch for: his ability to cut inside and take shots, plus his willingness to track back and defend, which makes him invaluable when Croatia needs to grind out results. Think of him as the guy who does all the dirty work while also being capable of creating magical moments out of nowhere.
