Sam Allardyce last night said he was "very shocked and disappointed" to have been sacked by Blackburn Rovers.
The Venky's Group, the club's new owners, announced last night that they have dispensed with the former Bolton Wanderers manager's services despite Rovers sitting relatively comfortably in 13th in the Barclays Premier League.
"I am very shocked and disappointed to be leaving Blackburn Rovers," Allardyce said in a statement released by the League Managers Association.
"I am extremely proud to have managed this club and I enjoyed a fantastic relationship with the players, my staff and the supporters during my time in charge.
"I now wish them and the football club every success for the future".
Allardyce's assistant Neil McDonald will also depart, with first team coach Steve Kean stepping into the breach temporarily.
The full statement from Rovers said: "The Venky's Group, owners of Blackburn Rovers Football Club, has today confirmed the departure of manager Sam Allardyce and assistant manager Neil McDonald with immediate effect.
"First team coaching duties will be taken on by Steve Keane for the immediate future.
"We have taken this decision as part of our wider plans and ambitions for the club. We would like to put on record our thanks to Mr Allardyce for his contribution to Blackburn Rovers Football Club."
