Two goals by Karim Benzema and one each from Kaka and Jose Rodriguez gave Real Madrid a 4-1 away win over third-tier club Alcoyano in the first round of the Copa del Rey on Wednesday.

Benzema headed in after Alcoyano defenders Javier Selvas and Arkaitz Perez failed to clear Alvaro Morata's cross in the 21st minute.

Alcoyano made a fast-passing start and had pounced on three of Madrid goalkeeper Antonio Adan's short clearances, causing Madrid to have to chase the ball hard in midfield.

''They played as I had expected - with joy, with intensity, with motivation and with self-belief because up until we started to score against them they even looked better than us,'' Madrid coach Jose Mourinho said.

Kaka controlled Benzema's assist outside the penalty area, took a step forward and hit a left-footed shot low into goal in the 35th.

The 17-year-old Rodriguez made a dream first team debut with Madrid when he scored in the 67th, before Javier Lara pulled one back for Alcoyano from a free kick in the 77th. Benzema scored his second from an assist by Kaka in the 87th.

Mourinho rested Cristiano Ronaldo, Mesut Ozil, Xabi Alonso, Pepe, Sergio Ramos and captain Iker Casillas.
