Martin O'Neill has been sacked by Nottingham Forest just five months after taking the reins.

The Northern Irishman has parted ways with the Championship outfit four days after his assistant Roy Keane stepped away from his position.

Forest named former Ivory Coast and Rennes manager Sabri Lamouchi as his replacement almost immediately.

The Frenchman played for Monaco, Parma, Inter Milan and Olympique Marseille.

"Nottingham Forest can confirm that manager Martin O'Neill has left the club," read a statement.

"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."

O'Neill and Keane were together for five years with Ireland and reformed their partnership when returning to a club they both played for.

O'Neill won two European Cups at the City Ground under Brian Clough but the reunion did not go as planned 

Forest finished eight points off the Championship play-off spots in ninth - the position they were in when O'Neill took over from Aitor Karanka. He became their 11th manager since 2011.

At his unveiling O'Neill said: "I'm here for 18 months and if I can’t get the club up then I will gladly hand it over to somebody else to see if they can do it."

Although a genuine charge at promotion didn't materialise when he came in, O'Neill would have expected at least a full campaign in charge to stamp his authority on the job. That, however, is a luxury he has not been afforded,
