Aitor Karanka has been appointed as Nottingham Forest's new manager on a two-and-a-half-year contract.
He replaces Mark Warburton, who was sacked at the end of last month, and takes over with Forest 14th in the Sky Bet Championship.
The 44-year-old was appointed as the manager of Middlesbrough in November 2013. He oversaw the team's promotion to the Premier League, but was sacked in March 2017.
He began his managerial career as the coach of Spain Under-16s before being named as Real Madrid's assistant manager in June 2010, where he worked under José Mourinho.
Chairman Nicholas Randall QC said he was "very pleased" with appointment the appointment in a statement on the club's website.
