Newcastle boss Sam Allardyce has warned the introduction of restrictions on when a manager could be sacked would bring further chaos into football.
Allardyce, an unabashed opponent of the transfer window system for players, is equally unimpressed with FIFA president Sepp Blatter's suggestion of similar rules aimed at curbing the frequency of managerial departures.
He said: 'Absolutely not. There would be utter chaos in that particular window like there is utter chaos in the transfer window.
'The transfer window is completely flawed, as far as I am concerned and I have always said that right from the very start.
'It creates inflation, it creates mayhem and it puts you in a hugely difficult position.
'To have a managers' window would cause even bigger chaos, as far as I am concerned.
'People just need to show a bit more faith and a bit more patience in the managers they ultimately choose in the first place themselves and give them the time they need to do the job and not to knee-jerk react.
'The need to be brave and true to themselves.'
Allardyce himself found his position called into question last weekend after Saturday's 4-1 home defeat by Portsmouth, despite it being just his 13th game in charge at St James' Park.
