Like dominoes, managers just keep on falling.

One after another have tumbled as club owners grow twitchy and impatient.

The “out with the old” maxim is alive and well within football circles.

Former Bantams boss Chris Hutchings was one of three to be fired on Tuesday, losing the Walsall hot-seat while Phil Parkinson was being turfed out at Charlton and Paul Simpson from Stockport.

And Roy Keane was the latest big casualty after his sacking by Ipswich was announced today.

Twenty-seven clubs – that’s well over a quarter – have changed managers since pre-season began in July.

But the sacking season only really gets going around the midway mark. Twelve have moved on in the last month alone.

And the midweek Premier League results left another four heads on the block. At least one of those will surely be chopped before long – if they haven’t been already.

A glance at the League Managers Association website shows Fred Everiss holds the record as the longest-serving manager. His tenure with West Brom spanned two world wars and 46 seasons!

Some now will be lucky to survive 46 games.

And it will get worse as foreign businesses eye football as their “get rich quick” card and clubs cave in to fan pressure because of a few angry message boards.

Yet each managerial vacancy will receive a sack load of applicants. The candidates keep coming back for more.

They must be gluttons for punishment.
