#3 Aaron Wan-Bissaka - €40m
Arguably the worst-affected individual by the aforementioned overload of talent in the English backline, Aaron Wan-Bissaka is yet to earn an international cap. Despite being a starter for one of the biggest clubs in world football, Wan-Bissaka has utterly failed to convince Gareth Southgate of his obvious talents.
With Trent Alexander-Arnold, Kieran Trippier, Kyle Walker and Reece James already on their books, England are blessed with some world-class right-backs. However, a boon for his national side has quickly turned into a bane for Wan-Bissaka.
The unlucky Manchester United stalwart came really close to making his international debut in 2019 after receiving a maiden call-up. Nevertheless, a last-moment injury meant the 23-year-old youngster had to forcefully withdraw from the international setup. Fast forward two years and Wan-Bissaka hasn't been able to earn another call-up to the senior squad.
#2 Christopher Nkunku - €43m
Fresh off scoring a Champions League hat-trick against Premier League giants Manchester City, Christopher Nkunku is in the form of life. The versatile attacker already has six goal involvements this season, putting him on track to eclipse his output of seven goals and 11 assists last term.
Nevertheless, Nkunku has been unlucky to have been born in France in the current era, with Les Bleus experiencing a golden generation in terms of talent. Regardless of his exceptional creativity and dribbling skills, the 23-year-old playmaker still finds himself on the periphery of the national team.
The former PSG graduate has excelled in his two years with RB Leipzig, dazzling audiences with some stellar performances at the Red Bull Arena. Still, he only has six appearances with the U-21 France squad to state under international experience. With budding prospects continuing to emerge in the French territory, Nkunku has a long road ahead of him in terms of a career in international football.
#1 Diego Carlos - €45m
Pipping Nkunku by a matter of €2 million, Diego Carlos has the record of being the most valuable player at the moment, without an international cap to his name. Despite his status as a seasoned center-back, Carlos hasn't had the opportunity to play for Brazil's senior squad to date.
While French prodigy Jules Kounde ends up hogging much of the limelight when it comes to Sevilla's masterful defending, his counterpart Carlos is yet to receive the appreciation he deserves. The 28-year-old defender has been instrumental in Julen Lopetegui's Sevilla project, proving to be an undroppable cog in the system.
Carlos was part of the Brazil squad that won a historic Olympic gold medal earlier this year, making six appearances in the tournament. Nevertheless, head coach Tite hasn't been able to find a role for the 28-year-old professional in his Brazil squad. Consequently, he remains the most valuable player in football with no official appearances on the international front at senior level.
