Real Madrid coach Zinedine Zidane had goalkeeper Moha in his squad for victory at Getafe yesterday.
The 17 year-old was called up in the injury absence of Keylor Navas and Zidane's son, Luca.
Moha's promotion actually saw him skip Castilla, with the teen still a member of Guti's youth team. He's yet to make his Castilla debut.
Moha joined Real three years ago from Tenerife and is a Spain U17 international.
