Albion have signed Spanish defender Inigo Calderon.

The former Deportivo Alaves captain was a free agent after leaving the second division club in the summer.

Calderon, 28, has made more than 250 appearances in Spain during two spells with Alaves and a stint with Alicante.

Boss Gus Poyet said: "I've known him for some time. He's powerful, good on the ball and brings something different to the club."
