Leeds United head coach Javi Gracia has been granted his work permit to start his new job.
The ex-Watford coach will be the Leeds boss until the end of this season.
Gracia has been given a simple yet challenging task - avoid relegation at all costs.
A club statement read: "Leeds United are delighted to announce Javi Gracia's visa has been confirmed. Following this, we are pleased to unveil a number of new additions to the existing backroom staff at Thorp Arch.
"Zigor Aranalde joins as an assistant coach, having served under Gracia in spells at Watford, Valencia and Al Sadd. Aranalde enjoyed a long playing career as a full-back in Spain with Eibar, Sevilla and Albacete, then in England with Walsall, Sheffield Wednesday and Carlisle United.
"Mikel Antia also arrives at the club as an assistant coach, having played alongside Gracia at Real Sociedad. The former centre-back, also enjoyed stints at Valladolid, Elche and Braga before moving into coaching and also has experience in England with Newcastle United.
"Juan Jose Solla is the final new recruit to the backroom staff, having worked alongside Gracia throughout his managerial career. Most recently working at French Ligue 1 side Marseille, he joins the Whites as fitness coach.
"Michael Skubala, who oversaw our two games against Manchester United and the match against Everton, will also remain in the first team setup. Paco Gallardo will now take charge of the Under-21s side, replacing Skubala at the helm."
