Kane as often been critical of the club and he's absolutely right, you can't sack a coach in round 5. It has to be done towards the end of the season.
Even if a club decides early on that the coach is gone, they won't do it early in the season. It will look unprofessional and panic laden.
Even if we're 0-10, I can't see him being sacked until about round 15.
I say roll the dice now. It can't get any worse.
