The Championship side announced earlier today that they had agreed a compensation fee with Bournemouth for Eddie Howe, who will return to the League One outfit after leaving Dean Court last year.
A joint statement was released, which said: "We are surprised and disappointed that Eddie is leaving a great club like Burnley so soon in the season.
"However, we understand that his decision reflects his personal circumstances rather than any matters at Burnley Football Club, be that supporters, the players or the board.
"We wish Eddie well in his future career and thank him for the hard work he has done at Burnley over the past 20 months. Eddie's sudden departure will not deter us from our plans and we are confident that the team will rally round while we seek his replacement - a search that has already begun."
Former Bolton Wanderers manager Owen Coyle is favourite to return to Burnley.
