just 19 goals from 27 matches, and he had disagreements with players, fans and the board). Club and manager parted ways by mutual consent, as the latter believed he could take the team no further. Nottingham Forest On 8 January 2018, Karanka returned to the Championship after being appointed as manager of Nottingham Forest. He replaced Gary Brazil, who had been acting as caretaker manager following the dismissal of Mark Warburton on 31 December 2017, who had in turn left the side sitting 14th in the league. His first match in charge saw Forest suffer a 1–0 defeat to Aston Villa, just days after his appointment. Karanka met his former club Middlesbrough for the first time on 7 April, where Forest were defeated 2–0. During his first summer transfer window in charge, prior to his first full season as manager, Forest signed João Carvalho from Benfica for £13.2 million, the club's most expensive transfer acquisition. Forest began the season very well, which originally saw them establish a five-match undefeated run. They continued their positive form up until December, where they only won one out of six matches during the final month of the year, which would ultimately cost Karanka his position. On 11 January 2019, he departed the City Ground after requesting to be released from his contract. He left the team in seventh position, four points behind the play-off places. A key reason behind Karanka's departure was the breakdown in relationship between him and Forest's Chief Executive, Ioannis Vrentzos. Forest's ambitious board were dissatisfied with Forest's play-off challenge and felt that the club should have been challenging for the automatic promotion places. Birmingham City On 31 July 2020, after 18 months away from management, Karanka was appointed head coach of EFL Championship club Birmingham City on a three-year contract. On 16 March 2021, the club confirmed that he had stepped down from his role after a run of just three wins in 19 matches left the team just outside the relegation zone. Former Charlton Athletic manager Lee Bowyer was announced as his successor shortly afterwards. AK Coaches' World In May 2021, Karanka organised an online coaching conference in association with the Royal Spanish Football Federation, under the name AK Coaches' World. The event focused on women's football, and participants included Ronaldo Nazário, Julen Lopetegui, Monchi, Iraia Iturregi, Jorge Vilda and Mila Martínez. Granada Following a 4–1 defeat at home
