Mikel Jauregizar

Key strength: Work rate

Box-to-box midfielder

As Athletic Bilbao's European ambitions hit turbulent waters—languishing in 5th place with just one win from their last five matches—one constant has emerged in Ernesto Valverde's turbulent campaign. Mikel Jauregizar, the 22-year-old Basque academy graduate, has become the heartbeat of Los Leones, amassing a staggering 43 appearances and 3,408 minutes across all competitions this season. While his 3 goals and 2 assists may not dominate headlines, the number 18's true worth lies in his inexhaustible box-to-box engine—his 68-rated passing knitting together attacks for Oihan Sancet and Nico Williams ahead of him. Valued at €30 million and climbing with every commanding display, the Spain U21 international embodies everything the famed cantera represents: technically assured, fiercely committed, unmistakably Basque. As Valverde scrambles to reignite his side's continental push, he knows his young midfield metronome will be ready.
