José Mourinho trusts 19-year-old Sergio Martínez for bench role at Real Madrid

José Mourinho, a coach historically associated with experienced squads and pragmatic roster management, is placing a teenager in his matchday squad and publicly declaring his trust in the kid.

The manager confirmed that 19-year-old central midfielder Sergio Martínez will be on the bench for tomorrow’s match, adding that the team trusts him.

From Racing Santander to the Bernabéu

Martínez’s journey to Real Madrid’s first-team bench has been remarkably swift. The young midfielder was playing for Racing Santander earlier in the season, where he announced himself by scoring on his La Liga debut.

Real Madrid activated his €3 million release clause in late August 2026. Martínez signed a contract running through June 2030, giving Madrid long-term control over a player whose ceiling remains unknown but whose floor already includes a top-flight goal. He’s officially registered with Castilla, the club’s reserve side, but has been training with the senior squad and appearing in matchday squads throughout the season.

Mourinho 2.0 at Real Madrid

Mourinho’s return to Real Madrid came in June 2026, marking his second stint at the club. His new contract runs through June 2029, giving him three full seasons to reshape the squad.

His first tenure at the Bernabéu, from 2010 to 2013, was defined by intensity, confrontation, and a squad built around proven winners.

Mourinho has cited trust in Martínez’s quality and maturity as reasons for his inclusion.

What this signals for Madrid’s season

Martínez is officially registered with Castilla but is participating in first-team training and matchday squads throughout the season. Madrid invested €3 million in a player who, if he develops as hoped, could be worth exponentially more within two or three seasons. If he doesn’t pan out at the top level, the financial downside is negligible by the standards of a club that routinely spends over €100 million on individual transfers.
