A second-half goal from Jon Ander Lasa settled a tight Basque derby at the Estadio de Erandio, leaving the hosts empty-handed despite a spirited display.

Match Overview

Erandio started brightly, pressing high and forcing several early corners. But Real Union Irun B, the reserve side of the historic Irun club, defended with maturity and gradually took control of midfield. The breakthrough came in the 58th minute when Lasa latched onto a through ball, rounded the goalkeeper, and slotted into an empty net.

The home side pushed for an equaliser, with Iker Zubizarreta hitting the crossbar from a free-kick, but the visitors held firm to secure all three points.

The winning goal came from a quick transition, exactly the kind of moment the visitors had been building towards.
