Club statement: "Burnley Football Club can confirm that first team manager Steve Cotterill has left the club by mutual consent."
Obviously this is the way that football clubs do it these days.
Nobody gets "sacked" any more. The contract is terminated by "mutual consent".
It is interesting to note Big Sam wants "five years to turn Newcastle around", yet Steve Cotterill was only at Turf Moor THREE years and he was the 12th longest serving manager in the Premier and Football Leagues and the longest serving in the Championship.
