Sam Allardyce has warned the introduction of restrictions on when a manager could be sacked would bring further "chaos" into football.
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."
