​Nottingham Forest have confirmed the departure of manager Martin O'Neill, with the Northern Irishman leaving the club just five months after taking over.

Sabri Lamouchi - former manager of Rennes and Ivory Coast - has immediately been named as O'Neill's successor.

O'Neill joined in January after Aitor Karanka was sacked, with the club then sitting in ninth place and six points off the play-offs.

Tasked with turning their fortunes around, the former Republic of Ireland boss failed to move his side up the table, as they ended up eight points behind rivals Derby County, who occupied sixth place, and they are now looking for their third permanent manager in a year.

​club statement read on O'Neill's departure: "Nottingham Forest can confirm that manager Martin O’Neill has left the club. The club would like to thank Martin for all his efforts during his time at The City Ground and wish him well for the future."

Lambouchi has immediately been confirmed as his stand in - though his title is head coach - and joins alongside six new members of staff. He led Ivory Coast to the 2014 World Cup and most recently managed Ligue 1 club Rennes for a season in 2017/18. In his playing days, he represented the likes of Marseille, Parma and Inter, while he earned 12 caps for France.

Forest will be hoping their next boss can finally bring an end to their 16-year spell outside the top flight and book their return to the Premier League for the first time since 2004.
