France great Zinedine Zidane handed his eldest son Enzo, 19, a debut for the Real Madrid reserve team on Sunday.

Enzo, a midfielder of great promise who usually turns out for the Spanish giants' third team, was promoted to the Real Madrid Castilla squad by his father, who is also the coach, for Sunday's match away to UB Conquense of Cuenca in the third tier.

He profited from the absence of several players due to international duty to appear as a late substitute in a match won 2-1 by Castilla.

Enzo, the eldest of Zidane's four sons, made his first appearance in the Madrid youth ranks in 2004 at a time when his father was starring for the club's first team.

He has dual Spanish and French nationality but has already been called up to the France under-19 set-up.

Castilla have won five and drawn two of their last seven matches to climb the table in Spain's Second Division B in Zidane's first season as coach.

In October, he was banned for three months for not having the necessary qualifications to coach in Spain, only to be allowed to continue while he appeals the decision.
