Zinedine Zidane declared himself proud as both a father and a coach after watching his son Enzo score on his senior debut as Real Madrid swept aside Cultural Leonesa 6-1.
A hat-trick from Mariano helped Real cruise into the last 16 of the Copa del Rey, with James Rodriguez notching another for Los Blancos while Cesar Morgado put through his own net.
Enzo Zidane replaced Isco for the second half to make his official debut, having appeared for Real during pre-season.
He marked his arrival in the 63rd minute when he drilled in a low shot following some neat interplay around the edge of the penalty area.
The elder Zidane said at his post-match press conference: "If I take my coach's hat off, I am happy for my son. I must also say that, as his coach, I am happy with him too.
"But not just with him, I am pleased with all of the players because they did a good job. When we get home I will speak to him, but as their coach, I am happy with them all."
Zidane added: "We produced a very disciplined display, we put them under pressure right from the off and we achieved the most important thing, which was to win with a good performance.
"Winning 7-1 away from home in the first leg made it difficult to come back here and put in a good performance. What I take away with me is the attitude and intensity that the players showed today.
"It is a special day for them, it is not every day that you make your debut at the Bernabeu."
Zidane maintains nothing will be settled either way when the LaLiga leaders travel to Barcelona for Saturday's eagerly-awaited Clasico.
"We are not thinking about the consequences of the result, only about preparing well for the game," he said. "Whatever happens it won't be decisive.
"It is a good match against a great opponent who will certainly make it difficult for us and that's all there is to it.
"We have to be ready. Now we need to rest up and we'll start our preparations tomorrow, but it won't be decisive, not at all."
