Sam Allerdyce never given enough time !!!!!!!!!!!!!!!!!!

Maybe the time has come for the premiership to change a few rules on the sacking of a manager.
Please, give me your opinion about what I'm going to say !!!!!!!!!!!!!!!!!!!!!
Personally, I think its about time that the FA creates a transferwindow for managers. With other words, you never hear of a player being sacked for not performing well enough. However, if a manager is not getting the results, they are the ones that are getting sacked. If I remember well enough, I believe that Everton didn't have any points out of the first 4 or 5 games of the season, but they stuck with their manager and see where they are now in the league. I think Sam Allerdyce didn't get enough time to build on what he wanted to achieve.
So maybe if the FA was to create a transferwindow in January and July, they would have to stick with their manager and that would take the pressure of them. It could also see a few upsetting scores towards the end of the term if the managers are getting desperate for results.
