Ayyoub Bouaddi (Morocco, aged 18) has showcased immense potential during the World Cup, establishing himself as a key figure in Morocco’s midfield. Known for his quick decision-making and ability to find forward options, Bouaddi combines strong ball control with an impressive height of 6ft 1in. His capacity to intercept and shield the ball underscores his football intelligence, making it likely that he will soon leave Lille for a more prominent club. To elevate his game, he must focus on scoring goals to become a more complete player.

Alex Freeman (USA, 21) has emerged as a standout performer under coach Mauricio Pochettino. As the youngest player in the squad, he has impressed at right-back, demonstrating maturity and composure in possession. After transferring from Orlando to Villarreal, Freeman's critical last-ditch tackles and ability to maintain possession have drawn attention. His bravery was evident when he scored the USA’s second goal against Australia shortly after a heavy clash, showcasing his quick footwork and defensive skills.

Tarik Muharemovic (Bosnia and Herzegovina, 23) has been a revelation in defense, playing left centre-back for Sassuolo. Standing at 6ft 4in, he has shown remarkable calmness under pressure and a high passing accuracy, consistently looking to break lines. Despite a sending-off against Switzerland for a last-ditch challenge, his overall performances have highlighted his potential, drawing comparisons to other young defenders making their mark in Europe.

Eli Just (New Zealand, 26) has gained recognition for his performances, particularly after a stellar season with Motherwell. His intelligent movement and ability to exploit defensive weaknesses have made him a pivotal player, especially in tandem with Chris Wood. Just's knack for scoring, with both feet, and his keen situational awareness position him as a player to watch for future transfers to bigger clubs.

Johan Manzambi (Switzerland, 20) rounds out this list of breakout stars, with his performances indicating he could also thrive in a top-tier league.
