Rafael Leão
One of the most electrifying athletes you'll see at this tournament, this Portuguese winger is essentially a human cheat code — he can go from standing still to full sprint so fast that defenders basically just watch him disappear. He plays for AC Milan in Italy and has become one of the most feared wide attackers in European soccer, combining that blistering pace with a surprisingly cool finishing ability once he gets into dangerous areas. Portugal already has Cristiano Ronaldo grabbing headlines, but Leão is increasingly the guy who actually unlocks defenses when games get tight. When you're watching Portugal, keep an eye on the left side — the moment he gets the ball with space in front of him, something exciting is almost certainly about to happen.
