I think the worse scenario, is not to sack him, then after a bad start , like Lee Johnson The Board sack him, so with the new season already begun, the choice of a new Head Coach is very restricted.
On a personal note, I do feel sorry, particularly as he has brought his family over, from Australia, but football is a results-business and finishing in the bottom 6 and the fact, that he was in charge for The League Cup semifinal v Aberdeen, where Hibs were playing against 10 men, but still managed to lose, all adds up to me, to say he hasn’t been good enough.
Finally, I would be surprised, if the new investors, would be prepared to give NM, for money to spend, but like a lot of things in Life, I could be wrong.
