We suffered a disappointing 4-0 defeat against Athletic Club as Yuri Berchiche’s brace and goals from Gorka Guruzeta Iker Muniain made it a night to forget at San Mamés.
Javier Aguirre continued with Cyle Larin as the leading striker, while new signing Nacho Vidal was named among the substitutes.
We could not have wished for a worse start as Yuri Berchiche flicked a set-piece into the bottom corner in the third minute.
The forward doubled the hosts’ lead in the 16th minute when he fired home from close range.
We found our feet after a tough opening as Antonio Sanchez had our first chance of the game when he fired over the bar from the edge of the box.
Athletic Club thought they had a penalty as we headed towards the break, but a VAR review ruled out what originally had looked like a trip on Inaki Williams.
The hosts had a handful of opportunities as the first half came to close, but we headed into the dressing room two goals down.
Predrag Rajkovic had to be at his best to deny Williams after the forward went through on goal, before Nacho Vidal almost had an instant impact on his debut with a powerful header.
Gorka Guruzeta added a third just past the hour mark when a low cross found him unmarked at the back post.
The hosts completed the socring in the 89th minute when Iker Muniain found the bottom corner from inside the box.
