Nottingham Forest have signed defender Daniel Ayala on a season-long loan from Premier League side Norwich City.
The Spanish Under-21 international becomes new manager Sean O'Driscoll's sixth summer signing.
Chairman Omar Al-Hasawi told the club website: "It is pleasing to sign a player with such a wonderful pedigree.
"He's only 21 but has experienced life in the Premier League, as well as the Championship and adds to the defensive resources at Sean's disposal."
Forest's defence has been weakened considerably by the summer exit of captain Luke Chambers and Joel Lynch.
Right-back Chris Gunter has also moved on, joining Reading - while long-serving centre-half Wes Morgan left for East Midlands rivals Leicester City in the January transfer window.
Spanish Under-21 internationa Ayala joined Norwich from Liverpool just a year ago, but spent much of last season out with knee and hamstring injuries and only started six Premier League matches.
