The Spaniard joins the club having previously coached at Athletic Bilbao, working his way up through the youth levels to become the goalkeeping coach for the first team, where he notably worked with now Chelsea goalkeeper Kepa Arrizabalaga.
During his playing career, the 46-year-old made nearly 200 La Liga appearances, turning out for the likes of Bilbao, Rayo Vallecano and Eibar.
The appointment will see him work with Dearden, as they look after the coaching aspect for Harry Isted, James Shea, Simon Sluga and Marek Stech, as we head into the new Sky Bet Championship campaign.
Welcome to Kenilworth Road, Imanol!
