The Youngest and Most Exciting:
Lennart Karl (Bayern Munich): At just 17 years, 3 months, and 24 days old, Bayern's attacking midfielder Lennart Karl made history as the youngest player to feature in the tournament. Coming on at half-time in Bayern's dominant 10-0 victory over Auckland City, Karl's early exposure to such a high-stakes environment underscores his immense potential and Bayern's faith in their academy.
Estêvão Willian (Palmeiras): Often dubbed "Messinho," this electrifying 18-year-old Brazilian winger is lighting up the tournament for Palmeiras. Already set to join Chelsea in July, Estêvão is using this global platform as a farewell showcase, proving why he's considered one of South America's most exciting talents.
Franco Mastantuono (River Plate): The 17-year-old Argentine sensation has already turned heads with his performances for River Plate. Linked with a blockbuster move to Real Madrid, Mastantuono is another prime example of a young prodigy making his CWC debut before a highly anticipated switch to a European giant, showcasing his precocious talent.
Desire Doué (Paris Saint-Germain): The 20-year-old French attacking midfielder has been a revelation for PSG this season, playing a crucial role in their Champions League final run. His CWC debut highlights his rapid ascent and maturity, proving himself on the biggest stages.
Jobe Bellingham (Borussia Dortmund): The younger brother of Real Madrid's Jude, 19-year-old Jobe made his Borussia Dortmund debut in the Club World Cup. His presence further solidifies his own burgeoning reputation and provides a fascinating subplot to the tournament, as he aims to carve out his own legacy.
High-Profile Transfers & Established Stars on Debut
Beyond the wonderkids, several established names and high-profile transfers are also gracing the Club World Cup for the first time with their new clubs.

He's already made an impact, scoring twice in Bayern's Round of 16 win against Flamengo.
Willian Pacho (Paris Saint-Germain): The Ecuadorian defender, a pivotal new signing for PSG from Eintracht Frankfurt, has quietly but effectively integrated into the French champions' backline. His CWC debut underscores his importance as a key component of Luis Enrique's defensive setup.
Julián Álvarez (Atlético Madrid): A World Cup winner with Argentina, Álvarez is now making his Club World Cup debut with Atlético Madrid after his transfer from Manchester City. His dynamism and goal-scoring prowess are expected to lead Atlético's attack as they aim for international glory.
Iconic Veterans in New Contexts:
Lionel Messi (Inter Miami CF): While a multi-time Club World Cup winner with Barcelona, his debut for Inter Miami CF, representing the host nation, is monumental. Messi's presence elevates the profile of the tournament, and his drive to deliver success for his new club on the world stage adds an extra layer of intrigue.
